在无线通信中，协作通信技术通过共享网络空间中其他用户的发射天线，使接收端获得空间分集增益，提高了整个系统容量。重叠时分复用技术通过时域信号的重叠提高系统的频谱效率。本文主要研究了递归重叠时分复用及其与协作通信结合后的系统性能。 首先，介绍了重叠时分复用(OVTDM)技术，递归重叠时分复用(ROVTDM)技术以及并行级联的ROVTDM技术。通过比较，相同重叠重数的情况下并行级联的ROVTDM系统的性能更具有优势。 其次，将OVTDM和ROVTDM系统和协作通信的中继，放大转发模式(AF）和解码转发模式(DF)分别结合，通过实验仿真得出结合后的系统在性能上都优于同频谱效率的AF、DF性能。在此还讨论了采用不同递归系数矩阵时系统的性能，结果显示完全递归的性能高信噪比的情况下才会略优于非递归系统，而其他递归的情况性能都不如非递归系统，但性能差别不大。 最后，将并行级联的ROVTDM与AF、DF结合的系统性能相比于OVTDM、ROVTDM和AF、DF结合系统的性能有很大改善，不但提高了频谱效率，并且在相同误码率下信噪比也有大幅度的降低。另外，由于并行级联系统中交织器对其性能的影响较大，所以分析了不同交织器对系统性能的影响，仿真表明采用S交织器的系统性能较好。

In wireless networks, cooperation communication is a novel technology that uses other user’s idol antenna to obtain the spatial diversity gain and improve the system capacity. Overlapped Time Division Multiplexing(OVTDM) improves the spectral efficiency by overlapping the time domain signal. This paper mainly studied the performance of recursive overlapped time division multiplexing and its application in cooperative communication. Firstly, OVTDM, recursive OVTDM(ROVTDM), and parallel concatenated scheme for ROVTDM(P-ROVTDM) are introduced. The performance of P-ROVTDM system is much better than OVTDM and ROVTDM with the same overlapped number. Secondly, combine OVTDM and ROVTDM with amplify-forward(AF) cooperative relay and decoded-forward(DF) cooperative relay, respectively. Experiments show that the performance of these new systems is better than that of the AF and the DF system under the same spectrum efficiency. The performance of the systems with different recursive coefficient matrix are also discussed, the results show that the fully recursive system is slightly better than the non-recursive one when the SNR is high, and other recursive systems is all worse than the non-recursive system, but the difference is slight. Finally, the performance of systems which combined P-ROVTDM with AF and DF are much better than the systems which combined OVTDM、ROVTDM with AF and DF. Not only the spectrum efficiency improves greatly, but also the SNR reduces a lot for the same BER(bit error rate). The paper analysis different interleaver’s influence on the performance of new system ,because of the great influence of interleave on performance in P-ROVTDM system. Simulation results show that the performance of the system using S-interleaver is relatively better.
