Abstract：In cellular mobile communication network, BPSK modulation symbol distribution optimization problem of multi array antenna system is the key for the inter-symbol interference suppression and channel optimization. BPSK code optimi-zation distribution algorithm of multiple array antenna system is proposed based on S transform and simulated annealing al-gorithm. Channel modeling of multi element antenna system is established, BPSK modulation symbol frame format design is taken. Gauss window function of S transform is used for the energy accumulation, time-varying, empty variable and the mul-tipath effect of signal are changed, and the transmission performance of the channel is improved. Simulation results show that the designed antenna system can effectively suppress interference, and optimize the antenna array distribution. The re-ceiving array channel impulse response gain is improved, and communication quality is improved.
