混合式二元加权合并器

Mixed binary weigted combiner

本文提出了一种新的两支路分集接收系统。它可根据两支路信号电平之比值来自适应地或是工作于等增益合并模式,或是工作于选择分集模式。采用此一技术,可以获得接近于最大比值合并系统的性能。文中进行了分析,并提出了两种实现方案及方框图。

A new type of two-branch diversity reception system is presented. It can work in ei- ther an equal-gain combining mode or a selection mode adaptively according to the ratio between the signal levels in the two branches. Using this technique the performance close to that of the maximal-ratio combining system can be obtained. An analysis is made and two implementing schemes are presented by using block diagrams.
