Performance in Characteristics Rayleigh Channel within DWT-OFDM with DAPSK Modulation for High Speed Communication Dr. Hussieny Yahya Ali AL University of Kufa, IRAQ Online published on 31 October, 2017. Abstract The advantages for using the OFDM system when it convert the wideband signal into narrowband signals for parallel transmission. And in the same time using DWT which captures both location information (location in time) and frequency that is temporal resolution as advantages over DFT. So that can using Rayleigh channel within their specification underlying DWT_OFDM system with DAPSK modulation. Using matlab simulation for this mode in this paper, it has produced a good performances in impulse response, frequency response, multipath channel and Doppler spectrum. Through them can provide a good narrowband fading which has minimum ISI & ICI and a wide variety of communication services such as high speed data. Top Keywords Matlab, ISI, ICI. Top | |
