The CDMA is uniquely featured by its spectrum-spreading randomization process employing a pseudo-noise (PN) sequence, thus is often called the spread spectrum multiple access (SSMA). As different CDMA users take different PN sequences, each CDMA receiver can discriminate and detect its own signal, by regarding the signals transmitted by other users as noise-like interferences. In this project Direct sequence principle based CDMA transmitter and receiver is implemented in VHDL for FPGA. The digital frequency synthesizer principle is used in generating the carrier signals both at transmitter and receiver modules. The transmitter module mainly consists of symbol generator, programmable PN sequence generator, digital local oscillator, spreader and BPSK modulator blocks. The receiver module consists of BPSK demodulator, matched filter, programmable PN sequence generator and threshold detector blocks. The CDMA receiver gets this input and recovers the data using matched filter. Modlesim Xilinx Edition 5.8 (MXE) tool will be used for functional simulation and logic verification at each block level and system level. The Xilinx Synthesis Technology (XST) of Xilinx ISE tool will be used for synthesis of transmitter and receiver on FPGAs. Applications of the developed CDMA system for ADHOC networks and defense communication links will be studied. The possible extensions of work in view of advancements in software defined radio principles will be discussed.","PeriodicalId":166647,"journal":{"name":"2011 IEEE Symposium on Computers & Informatics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130718331","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}

The presence of IPv4/IPv6 translation gateway violates the TCP/UDP intrinsic functionalities due to the translation of the IP addresses in IP packets. We address these interoperability issues by modifying IKE negotiation with NAT-Traversal capability and some improvements on IPSec software. However, the implementation of the conventional IKE authentication mechanisms such as pre-shared key and Public Key Infrastructure (PKI) certificate-based requires both nodes either to be manually configured, or to exchange the certificates and the necessity to enrol to certain Certificate Authority (CA). This paper proposes a new Internet Key Exchange (IKE) authentication based on certificateless public key infrastructure in order to alleviate the limitation of the conventional IKE authentication. We also propose an efficient public and shared parameters distribution mechanism whereby the translation gateway acts as Key Generator Centre (KGC).","PeriodicalId":166647,"journal":{"name":"2011 IEEE Symposium on Computers & Informatics","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126721181","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}
