一种新的Zero-Forcing BLAST联合检测算法

A Novel Combination Detection Algorithm for Zero-Forcing BLAST

在有效利用双向迫零(BID-ZF)检测算法和并行干扰消除(PIC)检测算法的基础上,提出了一种ZF-BLAST的联合检测算法:BID-PIC.仿真结果表明,这种新的算法在低复杂度的情况下可以获得比单纯使用BID-ZF或者ZF-PIC的性能好.

Based on two low complexity algorithms BID （Bi-Directional ZF） and PIC （Parallel Interference Cancellation）, we propose a novel combination detection algorithm BID-PIC of Zero-Forcing BLAST （Bell Laboratories Layered Space Time）. The novel algorithm efficiently uses the result of BID as an input of PIC. It is shown that the combination detection algorithm is better than the pure BID or Zero-Forcing PIC with low complexity.
