| 摘 要： | 码片均衡是提高第三代移动通信系统性能的关键技术之一。为了增强码片均衡器的性能,该文提出了一种新的码片均衡导频抵消Rake联合接收机方案,给出了导频抵消算法,分析了3种典型的码片均衡器及低扩频比下的Rake接收与导频抵消的一些特征。计算机模拟结果证明与码片均衡器相比,联合接收机无论在小扩频比还是大扩频比,一股信道还是严重失真信道的条件下,均有较大的性能增益。

| Abstract: | Chip equalization is one of the key technologies for improving the performance of the 3rd generation mobile communication system. In order to enhance the performance of the chip equalizer, a new scheme of chip equalizer jointed with pilot cancellation and Rake is presented in this paper. Computer simulations show that the new scheme effectively improves the performance of the receiver. |
