A BL-STBC for MU-MIMO SC-FDMA Systems

摘要

摘要: 该文提出一种适用于MU-MIMO单载波频分多址接入系统的块级空时分组码。利用这种码的代数性质和一个特殊置换矩阵，在线性最小均方误差准则下，导出了低复杂度多用户检测算法。通过仿真，给出了平均比特差错概率性能。与空频分组码相比，当SC-FDMA系统采用分布式子载波映射，块级空时分组码的性能具有优势，并且两者的计算复杂度相当。

Abstract: A Block-Level Space-Time Block Code (BL-STBC) is firstly proposed for Multi-User Multiple-Input Multiple-Output Single-Carrier Frequency Division Multiple Access (MU-MIMO SC-FDMA) systems. Next, employing the algebraic properties of the BL-STBC and a particular permutation matrix, a low-complexity algorithm is derived for the multi-user detector. Finally, the average bit error rate is given via simulation. The performance of the BL-STBC is better than the space-frequency block code, with no added complexity, if the distributed sub-carrier mapping is used.
