| Abstract: | Based on the principles of Monte Carlo,combined with the communication theo- ry of modulation and demodulation, the establishing of the Monte Carlo modeling simulation in digital communication system can analyzes the factors which influence the system performance with high efficiency. This paper analyzes the Monte Carlo modeling and establishes the Monte Carlo model for 8PSK communication system, and then analyzes the BER of 8PSK systems. Through the contrast of simulation results and the theoretical value, this paper verifies the influ-ence of SNR in communication system to BER by using the MATLAB. |
