In this paper, a multicarrier frequency hopping spread spectrum (MCFH-SS) system with girth-six low-density parity-check (LDPC) codes is developed as forward error correction scheme to improve its anti-jamming (AJ) capabilities. The paper also evaluates the bit error rate (BER) of girth-six LDPC codes with a column weight 3 for the given values of fractional bandwidth (ρ). It is found that the performance of MCFH-SS system with LDPC codes is significantly better than the system employing fast frequency hopping spread spectrum (FFH-SS) with girth-six LDPC codes in the presence of partial band noise jamming (PBNJ) over Additive White Gaussian Noise (AWGN) channel. At ρ =1, the BER of MCFH-SS and FFH-SS system is approximately 10−3 and 10−2 , respectively. This shows the effectiveness of MCFH-SS system with girth-six LDPC codes.

The paper is devoted to problem of spline approximation. A new method of nodes location for curves and surfaces computer construction by means of B-splines and results of simulink-modeling is presented. The advantages of this paper is that we comprise the basic spline with classical polynomials both on accuracy, as well as degree of paralleling calculations are also shown.

Field programmable gate arrays (FPGAs) have emerged as platform of choice for efficient hardware realization of computation intensive algorithms because of their intrinsic parallelism and flexible architecture. However, to achieve high performance, FPGA must be supported by efficient design methodology and optimization techniques. In this paper, FPGA-based design methodology and optimization techniques that can be employed to obtain area, speed and power efficient circuits are reviewed and presented.

Due to introduction of various wide-band applications in wired and wireless network demand of bandwidth is growing exponential. The existing network is not capable to meet the requirement of vast bandwidth. These requirement can be meet by all optical network which is capable of transmitting enormous data at very high speed, around 50 Tera bits per seconds (Tbps) A wavelength conversion technique is addressed in this paper to reduced the blocking probability in wavelength routed networks. It is seen that the blocking probability of traffic requests decreases as the wavelength conversion factor increases. We explode the possibility for network with different size comprising of 25, 50 and 100 nodes with variation in wavelength per link In this work the effects of varying number of wavelength converters, different traffic types on fiber link utilization and network blocking probability are evaluated and results are shown that the blocking probability is minimum with wavelength conversion factor of 0.5. Thus we propose a network with 32 and 64 wavelengths and 50 % wavelength convertible nodes.

This paper. presents a method for objects detection and features extraction in static video imagery that operates on color/gray-scale frames grabbed by common digital cameras or readily available images from external sources. Segmenting objects is achieved by a technique proposed here and named as direct thresholding (DTh) with background extracted through applying morphological background estimation scheme (MBES). The accommodating hardware is represented by a dedicated P4 PC-based image processing environment, whereas the intrinsic software has been simulated and validated using MATLAB7.3 platform. Human visual perceptual inspection plus histogramming showed an appreciable level of performance through a specific experimentation of multiple-phases. The envisaged diverse fields of application of this method may involve: traffic flow measurement of vehicles and pedestrians; athletic and dancing performance evaluation; public, private, and military security, and so on.

High transmission bit rate in futuristic mobile channels gives rise to severe ISI and this makes the detection task very challenging. Thus a smart detector such as Near Maximum Likelihood (NML) detector is needed and is the subject of study in this paper. Performance assessment of near-optimal NML detectors over such channels assumes great importance. Variation in performance of NMLD using different delays in detection has been assessed in terms of BER versus SNR curves. A number of different cases of mobile radio channels have been simulated in this work. These channels have different number of reflected paths with equal power distribution in the respective paths. The aim of this paper is to take a ‘worst case’ model of a mobile radio channel and then to investigate the performance of detectors in the receivers.

Bluetooth based new wireless applications can increase comfort and security by automation of the tasks earlier controlled manually. In this paper advantages of low cost, low power and robustness of Bluetooth have been exploited to propose and implement two new consumer systems in the form of a garage door opening system and an electronic attendance record system. Both the applications provide luxury of automation along with promise of a better security system and will thus be a step towards realization of a smart building environment. Bluetooth based garage door opening system helps to overcome the inconvenience to move out of the car for unlocking the door and it provides the luxury of keyless opening which is electronically controlled just by enabling the authenticated Bluetooth slave device. The other Bluetooth based application proposed and implemented in this work relates to automatic monitoring and recording of attendance of employees in an organization. Both the applications proposed and implemented in this paper offer better security, higher flexibility and lesser complexity. In this paper the applications are developed based on Bluetooth Link using Host Controller Interface and Asynchronous Connection Less (ACL) link.
