摘　　要：设计开发中继卫星系统仿真软件,并针对理想信道条件、I/Q幅相不平衡、幅频特性、群时延、相位噪声、功放饱和条件、非线性信道条件这七种信道,仿真16QAM和16APSK的误码率性能,并对仿真结果进行分析。利用仿真平台得出的非线性信道条件下误码率需求与所需信噪比之间的关系,可以作为完善系统技术指标的重要依据,为中继卫星系统后续建设和应用提供重要参考。This paper designs and develops the relay satellite system simulation software,and simulates the BER performance of 16QAM and 16APSK under the channel condition of ideal channel,I/Q amplitude and phase imbalance,amplitude and frequency characteristics,group delay,phase noise,power amplifier saturation,non-linear channel.The simulation platform gets the relationship between bit error rate and signal to noise ratio under non-linear channel conditions.The relationship is the important basis for improving system technical indexes,and the important reference for subsequent construction and application of the relay satellite system.
