Combined Chip Equalization Interference Weighted Cancellation Receiver for HSDPA
适用于HSDPA的码片均衡干扰加权抵消联合接收机

WCDMA needs to extend its downlink data rate to 10Mbps 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.
