Abstract

For a multi-cell CDMA system, we propose a partial decorrelator that decodes a user by suppressing the in-cell interferers only. As a result, each user suffers only from inter-cell interference and enhanced receiver noise. By analysis, we show that in random CDMA systems the partial decorrelator outperforms the conventional receiver, within the operating regime of the conventional receiver. By simulation, we show that under perfect power control, the partial decorrelator yields roughly 1.5 times the capacity of the conventional system
