  • 摘要:

    成對載波多址復(fù)用(PCMA)混合信號單通道盲分離性能界是衡量混合信號可分離程度以及分離算法性能的標(biāo)準(zhǔn)。針對PCMA混合信號，從發(fā)送信號模型出發(fā)構(gòu)造調(diào)制信號比特與符號的空間映射，利用最大似然準(zhǔn)則推導(dǎo)與混合信號分離算法無關(guān)的分離性能下界表達(dá)式，數(shù)值計(jì)算結(jié)果與理想情況下Viterbi仿真結(jié)果吻合，驗(yàn)證了所推導(dǎo)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.
