Abstract :
1xEV-DV is a 3G CDMA standard, capable of achieving data rates up to 3 Mbps. This standard employs high-order modulation (up to 16-QAM) which makes the detection at the receiver difficult, due to the multipath distortion. In this paper, we investigated the linear minimum mean square error (LMMSE) chip equalizer, as well as the parallel interference canceller (PIC), and their hybrid approaches, as applied to the 1xEV-DV downlink receiver. The results showed that the hybrid receivers perform excellently in all scenarios tested, and outperform previous art LMMSE and PIC receivers.
