为了减小无线信道的瑞利衰落，在ＣＤＭＡ系统中采用多路径合并的Ｒａｋｅ接收机．最大比合并是最佳合并，但在数字化接收机中难以实现．等增益合并实现简单，但在低信噪比的情况下，会恶化合并后的性能．为了在实现难度和性能上作折衷，提出了一种分区间加权合并的新算法，并给出了几种合并方案的性能比较曲线． In order to reduce the Rayleigh fading of wireless channels, a multipath combined Rake receiver is used in the CDMA system. Maximum ratio consolidation is the best combination, but difficult to achieve in digitized receivers. Equal gain consolidation is easy, but at low signal-to-noise ratios, the combined performance deteriorates. In order to make a compromise between the realization difficulty and the performance, a new algorithm of weighted combination between partitions was proposed and the performance comparison curves of several merging schemes were given.
