摘要 对采用排序串行干扰抵消(OSIC)检测的V-BLAST系统,提出了一种新的的天线子集选择算法。考虑到OSIC检测中排序和干扰抵消产生的影响,通过置换序列和QR分解,给出了一个非常简洁的且具有合理复杂度的V-BLAST系统的天线子集选择表达式。仿真结果表明该算法的中断容量曲线接近基于容量最大的最优算法,在性能上优于已有的几种天线子集选择算法。 A novel antenna subset selection in V-BLAST systems with ordered successive interference cancellation （OSIC） detection was presented. With an eye to the impacts of ordering and cancellation, by use of permutation and QR decomposition, a terse antenna subset selection mathematic expression with reasonable complexity for V-BLAST was put forward. Simulation results show that the proposed selection criterion achieves near-optimal outage capacity and outperforms several existing ones in performance.
