Performance Analysis of Aola Technique for Wireless Communication

In wireless communication, multiplexing & multiple access concept is most important. In most communication systems require, sharing of channels. In Multiple Access techniques types such as FDMA, TDMA, CDMA, & OFDM. OFDM based transmission system uses CP in an MB-OFDM symbol in order to maintain the orthogonality of Trasmission.Present days ultra-wideband systems use multi-band OFDM techniques for transmission in application like wireless personal area network(WPAN). UWB based system are power limited. cp introduces correlations in the transmitted data sequence &by using ZP suffix will have a flat psd. In the receiver ZP removal require use of a technique called as OLA. In this proposed, method we are implementing a rayleighpading channel placed by AWGN channel, adding ZP to increase the efficiency changing modulation technique for OFDM system. The simulation results shows the better results compared to the previous technique. Keywords-wireless communication, AOLA technique, rayleighpading channel.
