本文提出了一种新的两支路分集接收系统。
A new type of two-branch diversity reception system is presented.
因此在频率选择性衰落信道中，采用分集接收可以改善系统的捕获性能。
Therefore, system acquisition performance can be improved if diversity receiver is adopted for the frequency-selective fading channel.
最后证明了采用闭环发送分集方案，可以大大改善接收能干比，提高系统的前向容量。
Finally it is proved that the closed-loop transmission scheme can improve the receiving the energy and the interference ratio and increase the forward-link capacity of the system.
