In this paper, we analyze the CDMA forward-link capacity with macrodiversity and the results show that macrodiversity causes forward-link capacity loss whatever power allocation scheme is adopted.
本文深入分析了多天线宏分集下的CDMA系统前向容量并发现，在传统CDMA系统中，无论采用何种功率分配方案，宏分集都会导致前向容量损失。
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.
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。
Thus, this paper bring forward a young method to make up the lack of felt capacity-use mechanical joint element to link young and old concrete.
因此，本文研究的是加强新老混凝土结合，弥补粘结力不足的一种新方法，即采用机械连接件将新老混凝土结合在一起的方法。
