| 摘 要： | 推导了存在相位误差,正交误差和I-Q增益不平衡时,相干MPSK系统在莱斯信道下的误符号率,并以相干MPSK系统仅存在正交误差为例进行了仿真.仿真结果表明,该误符号率的数值解与已有文献相同,验证了理论分析的正确性.

| Abstract: | In this paper,symbol error probability of coherent MPSK(M-ary phase shift keying)system in rice channel is derived with the existence of phase error,quadrature error and I-Q gain unbalance.And the coherent MPSK system performance simulation of symbol error probability is also completed when there are only orthogonal error.The results show that,numerical solution of the achieved symbol error probability is the same with the existing literature,which is verified the correctness of the theoretical analysis in this paper. |
