摘要

在本文中，我们研究了该方案编码的DWT-OFDM系统与传统的OFDM系统在AWGN信道上的比较。考虑了16,32,64 - QAM和PSK调制方案来评估系统。此外，还使用了两种不同的小波来检测系统。利用MATLAB软件进行仿真。结果表明，在各种调制方式下，基于DWT-OFDM的系统性能都优于传统的OFDM系统

Performance Comparison of Proposed Scheme Coded DWT-OFDM System with that of Conventional OFDM

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
