摘要
空时分组码技术结合信道编码、调制和天线分集技术,当发送天线一定时,他的解码复杂度正比于发送速率,在3G标准中,该技术有着重要的地位。对空时分组码及相关知识进行了介绍,并对可变速率的空时分组码设计进行了探讨,最后展望了空时分组码技术的应用前景。
The space-time codes is a joint design of channel coding, modulation,antennas diversity. When the number of transmit antennas is fixed, the decoding complexity increases exponentially with the transmission rate. It plays an important part in the 3G standard. In this paper,the space-time codes and related knowledges are introduced,and then bring in the variable-rate space-time block codes. And finally, the future application usage of this variable-rate space-time codes is discussed.
