| 摘 要： | 在MIMO-OFDM系统中,基于软判决的检测算法其性能要明显优于基于硬判决的检测算法。传统的基于软判决的检测算法由于其很高的复杂度,从而对实现提出了很大的挑战。鉴于此,通过对软输出球形译码检测算法的研究,引入了一种快速有效的单树搜索球形译码检测算法。该算法极大地降低了MIMO软检测的复杂度,已应用于TD-LTE无线综合测试仪表的开发中。

| Abstract: | In MIMO-OFDM system,the performance of soft-decision detection algorithms is significantly better than hard-decision detection algorithm.Because the traditional detection algorithm based on soft-decision has high complexity,it results in a great challenge for the realization.Thus,through researching the soft-output sphere decoding detection algorithm,this paper introduces a fast and effective single tree research sphere decoding detection algorithm.This algorithm greatly reduces the complexity of MIMO soft detection,and has been applied to the TD-LTE wireless integrated test instrument. |
