摘要

摘要: 随着因特网与多媒体业务的需求,WCDMA引入了高速下行链路分组接入(HSDPA)技术将其下行链路数据传输速率提高到10Mbps。为了提高HSDPA传输的性能,该文提出了一种新的码片均衡干扰加权抵消联合接收机(LMMSE-IWC)。理论分析与计算机模拟结果表明LMMSE-IWC性能优于传统的Rake接收机和LMMSE码片均衡器。

Abstract: WCDMA needs to extend its downlink data rate to lOMbps or more because of the growing demand of the Internet and multimedia services. High Speed Downlink Packet Access (HSDPA) has been proposed to offer such high data rates in WCDMA technology within current 5MHz bandwidth. In order to enhance the performance of HSDPA, a novel receiver combined LMMSE chip equalizer and Interference Weighted Canceller (LMMSE-IWC) is presented. Theoretical analysis and computer simulations show that the performance of LMMSE-IWC is superior to conventional Rake, LMMSE chip equalizer.
