Abstract	:	Reduction of the power consumption in portable wireless receivers is an important con-sideration for next-generation cellular systems specified by standards such as the UMTS,IMT2000.This thesis explores the design-space for reducing the dynamic power dissipation ina RAKE receiver for the Direct Sequence Code Division Multiple Access (DS-CDMA)downlink. Starting with a reference implementation of the DS-CDMA RAKE receiver, wedemonstrate design methodologies for achieving significant power reduction, while high-lighting the corresponding performance trade-offs. At the algorithm level, we investigatethe impact of reduced precision and arithmetic complexity on the performance of the DS-CDMA RAKE receiver. We then present architectures for implementing the reference andreduced complexity DS-CDMA RAKE receivers, and analyze these architectures with re-spect to their dynamic power dissipation. Finally, we analyze clock-gating techniques forreducing the activity rate in both the architectures........-....,....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
