摘要:
成对载波多址复用(PCMA)混合信号单通道盲分离性能界是衡量混合信号可分离程度以及分离算法性能的标准。针对PCMA混合信号，从发送信号模型出发构造调制信号比特与符号的空间映射，利用最大似然准则推导与混合信号分离算法无关的分离性能下界表达式，数值计算结果与理想情况下Viterbi仿真结果吻合，验证了所推导性能界的合理性。
Abstract:Blind separation performance bound of Paired Carrier Multiple Access (PCMA) mixed signal is a measure of the separability of mixed signals and the performance of the separation algorithm. For the PCMA mixed signal, the spatial mapping of the modulation signal bits and symbols is constructed from the transmit signal model. The maximum likelihood criterion is used to derive the lower bound expression of separation performance independent of the separation algorithm. Numerical results agree well with the Viterbi simulation results under ideal conditions, which verify the rationality of the derived performance boundaries.
