SIMULATION OF FADING CHANNELS

Abstract

In this dissertation work, we have discussed different approaches of generating fading dispersive channel impulse response, which is used to model the desired Delay power spectrum and Doppler power spectrum. Then two simulation techniques, Monte Carlo method and Gaussian Quadrature rule are presented. A comparison of the two techniques based on simulation results is also presented. Finally bit error rate performance for frequency non selective fading channel over Rayleigh and Nakagami fading is presented. A tapped delay line model has been used to evaluate the performance of DPSK for frequency selective channel
