摘要
正交空时分组码和准正交空时分组码的编码速率≤1,为使空时分组码能够应用在高速传输的场合,本文提出了一种基于编码矩阵识别的高速空时分组码设计方法。该方法通过在发送端发送不同的编码矩阵表示不同的附加信息,能够实现大于1编码速率,仿真分析结果表明,在高信噪比条件下该方法使编码速率达到了2.5,并具有良好的有效吞吐容量,特别适合无线高速数据传输。
The coding rate of orthogonal space-time block code and quasi-orthogonal space-time block code are.To make space-time block code fit for high-speed communications,a high speed scheme is proposed by using matrices identification.The scheme employed different information controlling different coding matrices in transmitter,and provide the coding rate1.Simulation results show that the proposed method brings the coding rate up to 2.5.It can achieve large effective throughput,and especially suits for wireless high-speed data transmission.
