| 摘 要： | 本文提出了一种新的空时码——Hankel空时码。如果在多入多出(MIMO)通信系统中采用这种空时码,那么就能对MIMO系统的传输信道进行盲信道估计,也给出了相应的信道盲估计的算法。另外,相对于其它几种常用的空时码,所提出的空时码可以实现更高的传输速度。仿真结果表明在不同发射和接收天线个数、传输速率以及数据分组条件下,针对所提出的空时码的盲估计算法的性能。

| Abstract: | A new space-time code known as Hankel space-time code, is proposed. If this space-time code is used in Multiple-Input-Multiple-Output (MIMO) communication systems, MIMO channels can be blindly estimated. Moreover, the blind channel estimation algorithm is given. In addition, compared to other typical space-time codes, the proposed Hankel space-time code achieves high transmission rates. Simulation results are presented to demonstrate the performance of blind channel estimation algorithm for the proposed space-time code with various numbers of antennas, transmission rates and input packet sizes. |
