A New Technique for WCDMA Downlink Interference Cancellation
In this paper, we present a simple interference cancellation technique for the down-link of wideband code-division multiple-access (WCDMA) systems in multipath environment. With the same knowledge required by a RAKE receiver, the present method acts as an equalizer and cancels the interfering multipath signals from the received signal to retrieve the orthogonality property of the received signal. The present receiver has a simple structure and it has significant performance gain against the RAKE receiver. In addition, the noise enhancement is negligible when there is a line of sight path or the channel power delay profile has exponential decaying form.
