摘要

Alamouti編碼具有正交和傳輸速率1的特性，但是大於兩根以上的傳送天線上無法使用，而均勻線性陣列天線就是一種集束（beamforming）技術，可以將Alamouti編碼應用到多根傳送天線上提升整體的效能。

並列摘要

The Alamouti code is an orthogonal code with transmission rate 1, but it can’t be used in more than two transmitted antennas. The uniform linear arrasults show that has by (ULA) can be applied in the transmitter by using Alamouti code and the simulation reenterperformance.
