基于满分集空时分组码,提出了一种可获得满代数分集的非酉非相干空时编码方案,通过将其“等效”为酉空时码,对该编码的误码性能进行了优化.同时,通过充分利用文中编码方案的结构,提出了复杂度较低的分组广义似然比检验GLRT(generalized likelihood ratio test)解码算法.与现有酉空时码相比,仿真实验表明,此方案虽在信噪比方面略有损失,但其频谱效率较高,且GLRT分组解码算法能够对复杂度和性能进行较好的折衷. Based on full-space space-time block codes, a non-unitary non-coherent space-time coding scheme is proposed, which can obtain full algebraic diversity. The error performance of the code is evaluated by its “equivalent” The optimization of GLRT (generalized likelihood ratio ratio) decoding algorithm is proposed by making full use of the structure of the encoding scheme in the paper.Compared with the existing unitary time-frequency codes, the simulation results show that Although this scheme has slight loss in signal-to-noise ratio, its spectrum efficiency is high, and the GLRT packet decoding algorithm can better compromise in complexity and performance.
