Abstract
The purpose of this thesis is to model coherently detected BFSK, BPSK and QPSK, and noncoherently detected BFSK communications systems in the presence of additive white Gaussian Noise (AWGN) and different types of jamming signals by using MATLAB Communications Toolbox and Simulink. The theoretical results are available for the effect of AWGN on the performance of digital communication systems. To determine the performance of a system in the presence of AWGN and different types of jamming signals we need to use computer simulation. The results obtained by simulation are presented for bit-error rate (BER) as a function of signal-to-noise ratio (SNR) and signal-to-jamming ratio (SJR). As observed from the simulation results, different types of jamming affect each digital modulation technique differently.
