CDMA系统中数字化Rake接收机的合并方案
Combination Research in the Digital Rake Receiver of CDMA System
【摘要】 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.
【Abstract】 In order to relieve the Raleigh fading in wireless communication channels, Rake receiver is used in CDMA system for combining the signals from multiple paths. The combination method based on our simulation result is discused. We hereby propose a new combination algorithm, which can make a trade off between the performance and implementation complexity.
