Chip-Level Channel Equalization in WCDMA Downlink

Chip-Level Channel Equalization in WCDMA Downlink

<p/> <p>The most important third generation (3G) cellular communications standard is based on wideband CDMA (WCDMA). Receivers based on TDMA style channel equalization at the chip level have been proposed for a WCDMA downlink employing long spreading sequences to ensure adequate performa...
