HSDPA performance with parallel interference cancellation

Abstract

We investigate an advanced receiver technique called multistage parallel interference cancellation applied to high speed downlink packet access (HSDPA), which is a packet enhancement to the third generation wideband code division multiple access (WCDMA) mobile communication system. The advanced receiver packet error rate and throughput performance is compared to conventional rake receiver with link level simulations in single antenna case, and the results show that considerable gain is possible by using the advanced receiver in multipath fading channels, where the rake has already reached error floor.
