Performance Comparison of Proposed Scheme Coded DWT-OFDM System with that of Conventional OFDM
Authors
Abstract
In this paper, we have investigated the Proposed scheme coded DWT-OFDM system in comparison to conventional OFDM system over AWGN channel. 16, 32, 64 – QAM and PSK modulation schemes have been considered to evaluate the system. Moreover, two different wavelets have been used for examining the system. Simulations are performed using MATLAB software. It is found that proposed scheme based DWT-OFDM system performs better than conventional OFDM system under all the considered modulation schemes.
