A Family of Full Diversity Unitary Space-Time Block Codes

摘要

摘要: 对于接收端和发送端均不具备信道状态信息的MIMO系统，本文将Cayley变换与对角块正交空时分组码结合，提出了一种新的酉空时分组码构造方法。新构造的空时分组码适用于任意发送天线数为偶数的MIMO系统，能提供满发送分集度和1.5符号/信道利用的信息传输率，并可采用球检测法等低计算复杂度检测算法得到准最优的检测结果。

Abstract: For MIMO systems where channel state information is not acquired either at the receiver or at the transmitter, a novel family of full diversity unitary space-time block coding scheme is proposed in this paper, which combines Cayley transformation and the Diagonal Block Orthogonal Algebraic Space-Time (DBOAST) codes. The proposed space-time block codes can be applied to MIMO systems with even number of transmit antennas, which can achieve full transmit diversity and the rate of 1.5 symbol per channel use. The decoding of the proposed codes can be implemented by the sphere decoder at low computation complexity to achieve suboptimal results.
