The main objective of paper is focused on designing and then testing the performance of CDMA circuits implemented on FPGA. Main performance parameter of BER was chosen for simulation. The test performances are analyzed by simulating a CDMA communication system with QPSK modulation and demodulation. The latest technology advancement in cellular mobile communication systems has become more demanding for better quality of service. It requires broad bandwidth for huge quanta of data transfer. CDMA communication system easily meets these requirements of cellular communications. The design of the relevant circuits is based on CDMA approach of direct sequence spread spectrum technology. The functional performance of designed circuits is tested by carrying out simulations using Field Programmable Gate Arrays (FPGA) and Very High Speed Integrated Circuits Hardware Description Language (VHDL) on XILINX ISE® and MATLAB® platforms. The simulated results subsequently have shown quite improved and optimized circuit performance.","PeriodicalId":6426,"journal":{"name":"2013 International Conference on Emerging Trends in VLSI, Embedded System, Nano Electronics and Telecommunication System (ICEVENT)","volume":"21 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2013-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89625505","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A novel architecture, referred to the Selective Trigger Scan architecture, is introduced in this paper to address these issues. This architecture reduces switching activity in the circuit-under-test (CUT) and increases the clock frequency of the scanning process. An auxiliary chain is utilized in this architecture to avoid the large number of transitions to the CUT during the scan-in process, as well as enabling retention of the currently applied test vectors and applying only necessary changes to them. It also permits delay fault testing. Using ISCAS 85 and 89 benchmark circuits, the effectiveness of this architecture for improving Soc. test measures (such as, time, and data volume) is experimentally evaluated and confirmed.","PeriodicalId":6426,"journal":{"name":"2013 International Conference on Emerging Trends in VLSI, Embedded System, Nano Electronics and Telecommunication System (ICEVENT)","volume":"12 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2013-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82925076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the contributors to this is the PCB via commonly used in the multilayer PCB. In this paper the issues rising out of the via structure as well as how the via can be used to mitigate the issues is discussed. The vias provide a convenient way for routing electrical connections on different layers of the PCB. The discontinuities introduced by these vias on the PCB trace bring in new Signal Integrity (SI) and Electromagnetic Interference (EMI) related issues. These discontinuities lead to increased coupling and cross talk. This effect is prominent in differential traces containing vias placed nearby. In this paper, studies are carried out to estimate the effect of the via coupling alone separating it from the effect of the coupling from the traces. Different techniques for reducing these effects were tried out using commercially available tools based on numerical computational electromagnetics. The structures were analysed in the 1GHz to 10GHz frequency range. The results were validated using practical measurements.","PeriodicalId":6426,"journal":{"name":"2013 International Conference on Emerging Trends in VLSI, Embedded System, Nano Electronics and Telecommunication System (ICEVENT)","volume":"77 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2013-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83861475","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This uses to investigate the Residue Number System (RNS) to decimal equivalent binary conversion for the utilization of RNS numbers in Digital Signal Processing (DSP) applications. First, we simplify the Chinese Remainder Theorem in order to obtain a reverse converter that uses mod-(2n-1) operations. Next, we further analyze the theorem for the low complexity implementation that does not require the explicit use of modulo operation in the conversion process and we prove that theoretically speaking it outperforms state of the art equivalent converters. The proposed converter is implemented on Xilinx Spartan 3 field-programmable gate array. The results indicate that the proposal shows the better performance in conversion time, area cost and power consumption.","PeriodicalId":6426,"journal":{"name":"2013 International Conference on Emerging Trends in VLSI, Embedded System, Nano Electronics and Telecommunication System (ICEVENT)","volume":"11 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2013-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76237530","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A Magnetic Tunnel Junction (MTJ) is one such spintronic device which is not only used for memory storage but also for computation of logic functions. A multiplexer is an integral part of various digital logic circuits such as a FPGA. In the present paper, a novel architecture of a 2:1 multiplexer using only two MTJ elements, interconnected by a nano-magnetic channel has been designed. The corresponding demultiplexer has also been presented.

Similarly, the variation of threshold voltage with different doping density, channel length, channel thickness and oxide thickness of DG MOSFET are analysed. The inversion charge and electrical potential along the channel of double gate MOSFET are also discussed in this paper.

Again binary representations of these pixels are considered to hide secret information. Random bits from these bytes are used to replace the bits of secret. In this paper, many steganography techniques can be used like Least Significant Bit (LSB), layout management schemes, replacing only 1's or only zero's from lower nibble from the byte are considered for hiding secret message in an image. Along with these techniques, some more methods are proposed, based on selection of random pixels from an image and again secret data is hidden in random bits of these randomly selected pixels.

There are various methods of location management schemes for prediction of the mobile user. Based on individual characteristic of the user, prediction based location management can be implemented. This work is purely analytical which need the past movement of the subscriber. The movement of the mobile target is considered as regular and uniform. An artificial neural network model is used for mobility management to reducing the total cost. Single or multiple mobile targets can be predicted.
