| Summary: | 碩士 === 國立暨南國際大學 === 通訊工程研究所 === 98 === The aim of this thesis is to investigate the use of the finite state Markov channel (FSMC) model for analyzing the performance of cooperative communications over different fading channel environments. First, we discuss the case of different combining techniques in the ordinary Nakagami-m fading channel, and derive the necessary parameters used in the FSMC modeling process. Then, we employ the resultant FSMC model to analyze the performance of a cooperative communication system. The bit error rate (BER) with the decode-and-forward (DF) protocol is simulated through the derived model. After that, we also apply the FSMC model to examine the double Nakagami-m fading channel. This double Nakagami-m fading formulation is suitable for describing the mobile-to-mobile (M2M) communication scenario. With the FSMC model, we can obtain the range of the signal-to-noise ratio (SNR) and a number of states with different probabilities. We show that the FSMC model can successfully describe the double Nakagami-m fading channel as well, and can provide a fast simulation of the resultant BER performance in cooperation.
