摘要

本文提出了一套适用于四根发射天线的准正交空时分组码，在采用方格子星座的情况下，可以获得充分的分集和较高的编码增益。仿真结果表明，该设计与星座旋转的拟正交码非常接近。无需搜索最佳旋转角度和任何星座扩展，我们的新编码为QPSK和16-QAM调制提供了有利的传输方案

Constellation Expansion Free Quasi-Orthogonal Space-Time Block Codes on Square Lattice Constellations with Full Diversity and High Coding Gains

This article presents a set of quasi-orthogonal space-time block codes for four transmit antennas that achieves full diversity and high coding gain whenever a square lattice constellation is adopted. From the simulation results, the new designs perform very closely to quasi-orthogonal codes with constellation rotations. Without a search of the optimal rotation angle and any constellation expansion, our new codes yield an advantageous transmission scheme for QPSK and 16-QAM modulations
