摘要
Abstract
While space-time block code with complex signals can not provide full coding rate when the transmit antennas are more than two, the transmission matrix designed through constellation rotation can obtain maximum coding rate and full diversity gain in the meantime. The improved constellation rotated quasi-orthogonal space-time block code in this paper, whose signals transmitted by every antenna in different time belong to different constellations, improves the performance of the system with reducing inter-symbol interference and being advantageous to decode, when assuring maximum coding rate and full diversity gain.关键词
