Simulation system of 16PSK and performance analysis of BER

For the application of the 16PSK(Phase-Shift-Keying) to the wireless laser communication,this paper emphasizes the system of 16PSK's performance,theoretically.In the paper,the principle of the 16PSK's modulation and demodulation were introduced in brief and the performance of the system at two different signal channels was also analyzed and compared carefully.The above results provide the theoretical foundation for the wireless laser communication system based on the 16PSK with sub-carrier.
