The major problem of OFDM system is Peak to Average Power Ratio (PAPR) which reduces the efficiency of the system and increases the system complexity. In this paper, logarithmic based companding (i.e, mu law) and Square rooting companding (SQRT) have been suggested as simple and effective PAPR reduction techniques for OFDM. This paper analyzes mu law and SQRT companding OFDM signal on M ary QAM modulation technique. Simulation results show that the SQRT OFDM system is an effective technique in reducing PAPR and improved BER performance than OFDM system with mu-law companding transform. Comparison among mu law and SQRT companding techniques is made for the best suited companding technique for PAPR reduction in OFDM system. The Simulation result also shows that by modulating a signal at a fixed subcarriers for different modulation technique, the error in the transmitted data increases rapidly whereas in case of fixed modulation techniques, increasing the number of subcarriers the PAPR increases at the transmit, the bit error rate (BER) in the transmitted data is constant and varies by a small fraction.","PeriodicalId":286830,"journal":{"name":"2013 IEEE International Conference ON Emerging Trends in Computing, Communication and Nanotechnology (ICECCN)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116925941","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}

Accordingly Orthogonal Frequency Division Multiple Access (OFDM) technique based on Time Division Duplex (TDD) is an attractive technology for high data rate wireless access in multichannel communication. The modulation and demodulation of OFDM are done by Fast Fourier Transform (FFT) and Inverse Fast Fourier Transform (IFFT) respectively. In this paper we propose a Vedic algorithm for the implementation of multiplier that is to be used in radix 25 512-point FFT processor. The multipliers based on Vedic mathematics are one of the fastest and low power multiplier. It enables parallel generation of partial product and eliminates unwanted multiplication steps. Thus Vedic multipliers ensure substantial reduction of propagation delay in FFT processor. The FFT processor employing Vedic multiplier reduces hardware complexity in area and power in FPGA implementation. The proposed processor has been designed in Xilinx and implemented using Spartan 3E FPGA kit with a supply voltage of 1.2 V. The delay and power obtained using the Vedic multiplier are 173.60ns and 11×10-2 W respectively.","PeriodicalId":286830,"journal":{"name":"2013 IEEE International Conference ON Emerging Trends in Computing, Communication and Nanotechnology (ICECCN)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127726044","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}

However, research on low latency anonymity application including web browsing has received greater attention in order to preserve anonymity but it is quite impractical due to the enormous delay and extra bandwidth demand caused by the current dummy packet padding strategy against traffic analysis attacks. To overcome this problem, we propose a new packet padding strategy to replace the current dominant dummy packet padding strategy for anonymous web browsing systems. The proposed method uses prefetched pages as the cover traffic rather than the dummy packets. With the proposed model, we compared our proposal and the previous scheme in terms of the metric Anonymization Effectiveness (AE) theoretically. Moreover, we defined a metric to measure the efficiency of different padding strategies and established a mathematical model for the traffic analysis attack. Finally, the experimental results have shown that the proposed method is efficient in reducing the delay and bandwidth waste compared to that of dummy packet padding method which confirmed the potentials of the proposed strategy.","PeriodicalId":286830,"journal":{"name":"2013 IEEE International Conference ON Emerging Trends in Computing, Communication and Nanotechnology (ICECCN)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120946676","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}
