A Bit Error Rate model of M-ary PSK OFDM satellite communication systems for educational purpose

In this work, after a basic theoretical background on orthogonal frequency division multiplexing, our virtual bit error rate mode of M-ary PSK OFDM satellite communication systems, realised in Matlab, is presented. Elementary guide for the program is given: by simply typing the wanted parameters, communication system is defined. BER for this system can be plotted. This program is especially suitable for educational propose. Furthermore, in this work, influence of different PSK modulation, number of subcarriers and length of cyclic prefix on the signal performance and communication quality is analysed. It was shown that the BPSK gained the best signal performance, number of subcarriers has no influence on the transmission quality and by increasing the cyclic prefix BER is smaller.
