Designing a discrete-time controller in w-plane offers an advantage that the well-developed and well-recognized frequency response plots (for example, Bode plot) can be employed to design a discrete-time controller. The frequency response plots cannot be used directly in z-plane to construct a controller. However, this paper describes the difficulties and issues in constructing a discrete-time controller through a w- plane by the use of Bode diagrams/frequency response plots. For this purpose, one of the extensively used switching converters, i.e., a DC-DC buck converter operating at a switching frequency of 1000 kHz is considered as a plant. The problem arises due to the introduction of a right-half-plane zero (RHPZ) when one intends to transform a plant in s-plane to z-plane and then from z-plane to w-plane for the sake of designing a discrete-time controller in w-plane. RHPZ behaves as a pole and additionally lags the phase, thus making the plant nonminimum phase characteristically. RHPZ limits the system bandwidth and causes sluggish response. The control of plants containing RHPZ becomes complicated. MATLAB/Simulink based simulation results are presented to highlight the issues associated with construction of the digital controller in w-plane.

This research paper aims to find the performance difference of 3Com Core Builder 3500 Switch and Cisco 3550 Multilayer switch at various levels. There are 5 test beds designed to test the performance of these devices at individual level and then compare against each other. The topology used to perform these tests are very simple and easy to implement. Though collecting samples is easy, however it is time consuming. The data capture in all the tests is done using network analyzer tool, Wireshark and file transfer application called as FileZilla Server and Client. These tests are conducted multiple times to reduce the error rate which could have been a random number of 2% caused due to human and technical error. The results on the tests conducted are little surprising and complex than expected Cisco has a better data rate in all the tests performed with higher variations whereas 3Com had lower variations in all the tests it had a lower data rate than Cisco, again Cisco standard deviation is higher during bandwidth utilization. So as Conclusion Cisco's should be place in Distribution layer of a network as it is able to perform better at Layer 3.

To fulfill the extensive increase in the capacity and quality of multiple users, 5G next generation cellular network system is expected to be in the form of heterogeneous radio access networks (Het-RAN) [1]. It is expected to encompass small cells, known as macro, pico or femto cells. For such dense deployment, network operators have preferably deduced the mechanism of cloud networks called C-RAN due to their highly optimized operational efficiency and cost effectiveness. A centralized operating system which can easily be integrated with existing 4G/LTE networks is main aim of mobile phone operators. This approach reduces remarkably front haul overheads in C-RANs [2]. To expand the architecture of C-RAN, large number of antennas at access end majorly contributes to increase the network capacity either by improving the spectrum bandwidth or by increasing the number of active users at a specific time. Future 5G wireless and mobile communication operating systems require high transmission data rates and large channel bandwidth. Therefore, they can adopt millimeter-wave (MMW) band (30–300 GHz) as main operating frequencies to fulfill the requirements. In this paper, we focused on 60 GHz MMW frequency band. The potential benefits are, it is license free, large bandwidth ∼2 GHz, high oxygen attenuation that supports high frequency reuse and large number of components integration on small area (Massive MIMO). Moreover, we designed, simulated and optimized novel antennas suitable for implementing in the wireless devices of CRAN networks. In addition to compact, low cost, light weight, and ease of integration, the proposed antennas exhibit wide bandwidth above 4 GHz with an average gain values more than 12.5 dBi.

In fiber networks, non-linearity affects the performance of the system. In this research paper, the FWM (four wave mixing) is considered a challenge. To overcome the FWM non-linearity, the quality factors of the external modulation (electronic absorption modulation) with different optical filters (IIR, Butterworth, Bessel, Gaussian and Rectangle optical filters) have been simulated. A system with a bandwidth of 40 Gbps was studied at four different channels with the spacing of 5 nm and capacity of each channel is 10 Gbps. After thorough analysis for obtaining a better quality factor, the Rectangle optical filter is finalized. By obtaining good quality factor, we achieved a 40 Gbps WDM system with a link length of 150 km. currently intermediate line amplifiers are being placed approximately every 80–100 km to compensate the link losses.

A large number of precious lives are lost due to road traffic accidents every day. The common reasons are driver's mistake and late response from emergency services. There is a need to have an effective road accident detection and information communication system in place to save injured persons. A system that sends information messages to nearby emergency services about the accident location for timely response is absolutely in need. In research literature, a number of automatic accident detection systems are proposed by numerous researchers. These include accident detection using smartphones, GSM and GPS technologies, vehicular ad-hoc networks and mobile applications. The implementation of an automatic road accident detection and information communication system in every vehicle is very crucial. This paper presents a brief review on automatic road accident detection techniques used to save affected persons. An automatic road accident detection technique based on low cost ultrasonic sensors is also proposed.

The overwhelming proportion of cellular data communication originates from the indoor usage of smart phones, tablets and other such devices. To facilitate higher bandwidth, future systems are transitioning to higher frequencies (> 2 GHz). However, there is a high penetration loss due to walls etc., when outdoor base stations communicate with indoor devices. To overcome this issue, the use of indoor femtocell base stations has emerged as a popular solution. This work aims to analyze the impact of offloading outdoor users to small cells. The outdoor users are initially served by macro network i.e. network consisting of outdoor base stations only (macrocell base station or eNodeB) and are then progressively handed over to femtocell base stations and small Densification is done by installing femtocell base stations within the coverage of eNodeB, this densification is one of the key enabling technology for future 5G cellular networks. We analyze the network performance in terms of the overall capacity gain, peak user equipment (UE) throughput, macro cell edge throughput and overall coverage enhancement. The offloading results in significant improvement in all of these aspects at the cost of additional network deployment cost.

Orthogonal Frequency Division Multiplexing (OFDM) is a promising modulation technique because of its ability to handle multipath frequency selective channels with a simple receiver. The objective of this project is to design and implement a baseband OFDM transmitter and receiver on FPGA hardware and MATLAB. The work includes designing of easily reconfigurable and adaptable modules for modulation and demodulation, synchronization, channel estimation, equalization under AWGN and multipath Rayleigh channel. A separate header file is made in FPGA that includes all the parameters that can be reconfigured without changing the rest of the design implemented. All modules are designed on MATLAB as well as on FPGA using Verilog programming language and implemented on Spartan 6 board. Chip scope is used to provide interface between user and the hardware. Results are compared with theoretical results provided by MATLAB bit error tool.
