QPSK SIMULATION BASED ON MATLAB PROGRAMMING

HOU Zhou-guo,QIAN Sheng-you(Department of Electronics,Hunan Normal University,Changsha 410081,China)  
This paper introduces the modem theory and process of QPSK in the digital communication.It also addresses a method for programming with Matlab to analyze the QPSK system and describes how to emulate the system separately via ideal signal channel and interfered channel.With Monte Carlo analysis to simulate the QPSK channel,it is found that the BER (bit error rate) and other results of the computer simulation can get the same performance as the ideality.
