A low-power DS-CDMA RAKE receiver utilizing resource allocation techniques.

A low-power DS-CDMA RAKE receiver utilizing resource allocation techniques.

This paper presents architectural and implementation innovations made to realize a self-contained front-end processor for any DS-CDMA-based system. At the heart of the ASIC is a highly flexible RAKE processing engine that utilizes a unique resource allocation technique for maximum flexibility. The f...
