This report presents the highlights of the studies and investigations on various channel models and various channel coding schemes. These studies aim to improve the system performance by adopting suitable channel coding schemes. Reviews on past research findings on different channel models and channel coding, particularly on additive white Gaussian noise (AWGN) channels or fading channels with error correcting codes will be presented. Theories of both the digital and wireless communication systems will be shown, especially into the understanding of different types of channel model and different types of channel coding. Simulation of different channel models over the binary phase shift keying (BPSK) modulation and the resulted bit error rate (BER) of those simulated channel models over different channel coding will be presented. The simulation is divided into parts such as simulation of different channel models without channel coding, simulation of the characteristic of the different channel coding and, lastly, simulation of different channel models using different channel coding. All simulations are done in the MATLAB environment to investigate on the system performance and adopt suitable channel coding schemes. In this report, the performances obtained from the simulations of the coded transmission systems in the various channel models are shown to have significant improvement than the uncoded system.
