Performance study of AWGN channel and Rician fading using R-S code apply in DVB / Nor Izatul Asiah Md Nordin

This thesis is highlight the performance of Additive White Gaussian Noise (AWGN) and Rician fading that being apply in Digital Video Broadcasting (DVB) by using 256 Quadrature Amplitude Modulation (256-QAM) and 1024 Quadrature Amplitude Modulation (1024-QAM). The modulation technique that is used in this thesis is QAM. The purpose of using this modulation technique is because of to increase the spectral efficiency. This thesis also use Reed-Solomon codes as the encoder and decoder in able to correct and detect any error that is occurred in this communication. The main objective of this thesis is to know which channel that give better performance either by using AWGN as the channel or using Rician Fading as the channel. During the transmission of the signal the noise will be added and for this thesis the noise that is added is either AWGN or Rician fading. The performance of this thesis will be evaluated by using the MATLAB software version 7.6.0. The AWGN and Rician fading is be compared in terms of bit error rates (BER) and signal energy to noise power density ratio (Eb / N 0 ). The model consists of transmitter, transmission channel and receiver.
