频率选择性衰落信道下空时分组码盲识别技术综述

摘要

空时分组码盲识别技术是通信信号盲识别技术中一个新的重要方向,在频率选择性衰落信道条件下对空时分组码盲识别进行研究具有十分重要的现实意义.论文首先介绍了频率选择信道下对空时分组码盲识别研究的意义,分别在单载波和多载波条件下对空时分组码盲识别类型识别方法进行分类,并概述了每种算法的关键识别思想,并对其进行了对比总结,最后展望了在频率选择性衰落信道下的空时分组码识别算法的难点和未来趋势.%Blind identification of space-time block codes(STBC)is a new important direction in communication signal blind identification technology,especially under the condition of frequency-selective fading channels,which has very important practical significance. Firstly,the significance of blind identification of STBC is introduced. Secondly,the category of STBC blind recognition in single carrier and multicarrier transmission is illustrated. Then,the key of each algorithm is summarized and carried on the con?trast. Finally,the difficulties and the future trend of STBC recognition algorithm are indicated.
