Based on the overall design of mobile communication system, this paper establishes the system analysis model when the mobile communication system is affected by the co-channel interference. Combined with the diversity reception technology, this paper analyzes the performance of the mobile communication system under the conditions of Gaussian white noise (AWGN), co-channel interference (CCI) And Rayleigh, Ricean, and Nakagami environments, the BER performance of MQAM with Efficient Spectrum Modulation (MQAM) is derived and a general approximation formula for bit error rate is derived. Finally, through the analysis of computer simulation results, we get some conclusions.
