Abstract

Reliable path selection prior to maximum-ratio combining is a crucial operation in any DS-CDMA receiver. We propose a simplified dynamic threshold rule for path delay selection. The new threshold rule is based on the statistical parameters of the interference, which can easily be estimated from the computed power delay profile. By using the new threshold rule, the performance of the RAKE receiver can be improved and/or its complexity can be reduced, considerably
