摘要

本文将改进的多级球面译码(IMSD)算法引入到MMSE-PIC迭代结构中，提出了一种新的高阶调制MIMO系统联合迭代检测结构。IMSD算法是针对高阶调制系统设计的，具有较低的复杂度和接近SD的性能。在原MMSE- pic结构的第一轮迭代中，新结构用IMSD检测器取代了MMSE线性检测器，具有更好的性能和更低的通道相关灵敏度。

A new joint iterative detecting algorithm in high-order modulation MIMO systems

This article imports an improved multistage sphere decoding (IMSD) algorithm into the MMSE-PIC iterative structure and proposes a new joint iterative detecting structure in high order modulation MIMO systems. The IMSD algorithm is designed against the higher-order modulation system with lower complexity and near SD performance. The new structure replaces the MMSE liner detector with the IMSD detector in the first round iteration of original MMSE-PIC structure, which has better performance and lower sensitivity towards channel correlation.
