摘要

使用晶格约简(LR)已被证明是一种非常有效的方法，信号检测在多天线系统。本文研究了多输入多输出正交频分复用(MIMO-OFDM)系统中的次最优软输出最大后验(MAP)检波器的栅格降维性能。我们提出了两种多项式时间方法来在约简格中生成期望大小的候选列表。采用这些列表生成方法的次优软输出MAP检测器在不相关的MIMO-OFDM系统中提供了接近最优的性能，但显著降低了计算复杂度

Sub-Optimal Soft-Output MAP Detector with Lattice Reduction in MIMO-OFDM System

The use of lattice reduction (LR) has been shown to be a very effective method for signal detection in multiple antenna systems. In this paper, the performance of the sub-optimal soft-output maximum a posteriori (MAP) detector with lattice reduction is studied in multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) system. We propose two polynomial-time methods to generate the desired size candidate list in the reduced lattice. The sub-optimal soft-output MAP detector with these list generation methods provides a near-optimal performance in uncorrelated MIMO-OFDM systems, but with significantly reduced computational complexity
