摘要
针对降低路径间干扰,将传统的Rake接收机同均衡器相结合,提出了一种CDMA系统低扩频比下的低 复杂度接收机结构.计算机仿真表明该Equalizer-Rake接收机同传统的Rake接收机和同等复杂度的chip均衡器 相比性能有较大改善.
In the CDMA system, the inter-path interference (IPI) becomes very serious when the spreading factor is low. In order to decrease IPI, a low complexity receiver structure in the low spreading factor for the CDMA system which combines the conventional Rake with chip equalizer is proposed. Computer simulation shows that the Equalizer-Rake receiver performs better than Rake and chip equalizer with equal complexity.
