Integrated Power Amplifier (PA) and filter which is part of important component for Radio Frequency (RF) transmitter is designed using Adavance Design Simulation (ADS). The main aims of the design is to provide linear amplifier and filter at the center frequency of 2 GHz and biased at the conditions of class AB. GaAs transistor is used as an active device due to ability in operating at high frequencies and can generate signals with lesser noise. Linearity of the integragted design was simulated with two tone test and the intermodulation products (OIP3) value resulted to be 50 dBm. ACPR of -50.86 dBC with 10MHz frequency spacing is achieved using the Butterworth Bandpass Filter. On the other side, high linearity will lead to more efficient transmission of the signals.

This paper presents the reviews of few previous works for low noise amplifier design (LNA). This paper will explore several recent architectures of LNA but focused on four techniques of topologies which are forward body bias, self-biased inverter, common source cascade and cascode technique. Those architectures are able to minimize power consumed in a typical CMOS for wireless sensor network (WSN). Besides, high gain, low noise, input and output matching are also reviewed. As to provide extremely low power and also optimized all characteristics aspects, the performance for each topologies then are discussed. Further research will be conducted based on these four topologies comparisons in order to design a new successful LNA.

This research paper implements a 3D tetrahedral meshing frequency solver to simulate the electromagnetic effect of triangular tip (TrT) and tapered tip (TaT) added to a circular split gap. Behavior of circular rings placed inside a standard WR159 waveguide with preference to the conventional circular split ring was modelled. TrT and TaT structures optimization and validation was made using five well known algorithm namely PSO, GA, CMAES, IQN and CP. With TaT, the less electrical field sensitivity of the conventional circular split ring improved from 5.19e+04 V/m to 5.36e+04 V/m. While the magnetic field sensitivity value rises from 149 A/m to 218 A/m, a 3.27 % increase. At the same time retaining the resonant frequency well at 6.0 GHz even with TrT and TaT. The approach of this integration can be used to design numerous novel C-Band metamaterials, communication and future millimeter wave applications.

Wireless networks are broad area that experiencing rapid growth in this last few decade and can be categorized into two sub-domains. Correspondingly, wireless ad hoc networks is one of the sections in wireless networks, it can be further categorized based on the applications. This paper focuses more on vehicular ad hoc networks (VANETs) which fall into one of the applications in wireless ad hoc network. Area of interest in VANETs research has been summarized and medium access control (MAC) research area is still wide area to be discovered. VANETs performance metrics also has been outline. Cooperative communication on the other hand is a noted technique to enhance reliability and throughput in wireless systems where the neighboring nodes can do the overhearing. Cooperative MAC protocols do receive much attention from researchers' especially in IEEE 802.11 standard and a summary of related works had been done. A strong relationship between cooperative MAC protocols has been reported in the literature but only a few focuses on vehicular network. Since cooperative communications is a promising technique in improving reliability and throughput in wireless system, this can be implemented for V2V scenario in vehicular networks.

Video restoration has been an interesting area of research for many years and still with the advent of new technologies makes it an important subject to be discussed. Blotches are common defects in old archives. They refer to a small area with an approximately uniform gray level that occurs randomly in each frame. After applying most algorithms to detect the position of blotches and also scratch which is another type of defect in the old media, in each frame of video, it is essential to correct them, in other words, we should fill the missing data with reasonable values. In this paper, we consider this task similar to an optimization problem and apply Genetic Algorithm (GA) to each frame. The current frame scans row by row and is considered as the corrupted slice of each row which is found; then, we apply the GA to fill the missing data on that special portion and the process is continued to cover the image completely. The proposed algorithm is able to remove blotches and scratches with different sizes and directions and shapes. The information of previous or next frames is not needed in this implementation. The experimental results show the restored images have good quality.

With the growing use of the Global Positioning System (GPS) in many fields (air, land, sea and space) as advanced navigation system which provide high accurate and reliability for the position (latitude, longitude and altitude) and velocity with time. Multipath is one of the contributing sources of errors that impact on the precision and reliability of GPS. This paper investigates impact of multipath error on the GPS system by using a specially designed simulator platform to simulate multipath interference of the satellite electromagnetic waves and also to evaluate the accuracy of the system with different velocity by using private car. In our tests, we have used GPS receiver card model (GARMIN GPS 25-LVS) is the sensor board of the Global positioning System designed for a wide spectrum of OEM (Original Equipment Manufacturer) with antenna model GA 25 MCX.

Data replication is an increasingly important topic as databases are more and more deployed over distributed systems, grid community and clustering systems. The performance, reliability and portability of entire database may possible by using replication technique. Replication may be considered as a data backup policy. Replication in homogeneous system is common practice in real life, but replication in heterogeneous system is quite challenging, because of the dissimilar computing environment. Since the computer environment porn to be heterogeneous, hence it's a promising field for researchers to consider replication in heterogeneous environment. In our research a persistence layer has been proposed for replication in heterogeneous systems. This persistence layer work on asynchronous model, hence it may call as asynchronous replication model. The model works implements multi threading technique for creating parallel connection with peer servers. The main server and replicated server are connected with a common interface. The interface is a replication engine, which intelligently holds data and makes decision depending on different factors for sending data to smoothen the replication process. The whole structure follows the rules of SOA (Service oriented architecture) thus, modification of replication servers do not affect the main server. Finally the architecture of this concept builds on different configurable files. These files help us in system up-gradation without shutting down the system. At the end, some experiments have been carried out and the results have been analyzed.

In the production of nanostructured TiO2, the annealing temperature for the film is differed to clarify that by the use of different temperature in annealing the film, the best temperature to get a good mobility for the current flow can be found. There are 7 samples with different drying temperature and different annealing temperature. The ones with different drying are not annealed and the other that has the same drying is discussed based on different annealing temperature. Which one will have the highest IV characterization. As further discovered that the as deposited without annealing have a quite thick film that it could not be characterized by Atomic Force Microscopy (AFM), so only the thinnest that is a 500°C annealed film can be characterized using AFM. The highest point of the current at 10V in the IV graph is 500 C annealing temperature of 6.06E-9 which then makes it the highest in conductivity at 3.37E-6. The current-voltage (I-V) measurement is used to study the electrical resistivity behaviour, hence the conductivity of the film.

Security becomes the critical issue in incoherent spectral amplitude coding optical code division multiple access (SAC-OCDMA) systems. In preventing the unintended users from decoding and extracting the data due to the cross-correlation among code sequences, an ideal detection technique is needed to enhance the security of the SAC-OCDMA systems. In this paper, we study the efficiency of the modified-AND subtraction detection technique as well as conventional AND subtraction detection technique in towards the confidentiality issue. The OptiSystem software is used to simulate the system performance of the mentioned detection approaches. Based on enhanced double weight (EDW) codes, the simulation results revealed that the modified-AND subtraction detection improves the confidentiality of SAC-OCDMA system compared to the conventional AND subtraction detection. The modified-AND subtraction detection technique manage to secured the data from the unintended users to make them only detected a noise with interferer bit-error rate (BER) = 1 and Q-factor = 0.

This paper discusses the comparison between two modulation systems, pulse code modulation and delta modulation. The objective is to identify a suitable modulation for speech coding by comparing delta modulation (DM) with pulse code modulation (PCM). The reconstruction performance of the delta modulation is compared with the pulse code modulation by using MATLAB, SIMULINK and finally implemented DSP Processor for real time realization. The simulation result using SIMULINK shows that the delta modulation performs better than pulse code modulation. Hence, delta modulator is implemented for real time test on DSP board, TMS320C6416. Delta modulation is successfully implemented in real time realization and can be further improved to reduce noise for future works.
