Alamouti方案的仿真与性能分析

Simulation and Capability Analyzes of Alamouti Scheme

Alamouti方案是为发射天线数为2的系统提供完全发射分集增益的一种空时分组码方案,介绍Alam-outi的一种简单的发射方案,包括编码和译码算法及其性能分析,并使用Matlab仿真了Alamouti方案的两发射一接收的情形.

In the history of the development of code, the Alamouti scheme is the first kind of space-time block code which provides the full transmitting diversity with two transmit antennas. It is noticeable that although Delay Diversity Code （DDC） scheme can also realize the full diversity. But Mamouti Scheme can bring in interfere between the marks, and the receiving end needs the complex examination circuit simultaneously. This article introduced one kind of simple Alamouti＇ s launch scheme, including the code algorithm, the decoding algorithm and the capability, and do the simulation of Mamouti＇ s scheme with MATLAB which has two transmit antennas and one receive antenna.
