In this paper, spatial channel pairing (SCP) is introduced to coherent combining at the relay in relay networks. Closed-form solution to optimal coherent combining is derived. Given coherent combining, the approximate SCP solution is presented. Finally, an alternating iterative structure is developed. Simulation results and analysis show that, given the symbol error rate and data rate, the proposed alternating iterative structure achieves signal-to-noise ratio gains over existing schemes in maximum ratio combining (MRC) plus matched filter, MRC plus antenna selection, and distributed space-time block coding due to the use of SCP and iterative structure.


概要:在单中继系统中,对于给定空间信道配对(spatial channel pairing, SCP)方案,可以推导出最佳相干合并的闭式解;对于给定相干合并方案,也可以得到SCP的近似解析解。由此,本文设计了一种基于SCP和相干合并的交替迭代结构。仿真结果表明:相较于现有的最大比合并加匹配滤波,最大比合并加天线选择以及分布式空时码算法,本文提出的交替迭代结构能够提供更为可观的信噪比增益。
