Bits error rate calculation of bpsk and qpsk using matlab

In order to choose the most suitable modulation, several criteria such as power efficiency, bandwidth efficiency, and bit error rate are used for evaluation. This paper focuses on error performance of phase modulation schemes in different channel conditions and on the method to reduce bit error rates with the help of convolutional coding which is extensively used in GSM cellular system's encoder. A brief description of theoretical aspects of phase modulation schemes commonly used in satellite communications such as BPSK and QPSK is also given here along with simulations carried out with the help of Matlab and Ansoft Serenade tools.
