Abstract

This paper presents a programmable hardware platform for dual-mode WCDMA/OFDM receiver implementations. The platform is targeted for mobile terminals capable of operating in tight coupling UMTS-WLAN interworking systems. The proposed platform comprises a RISC core and three coprocessors that are used for the most intensive computation kernels. The receiver algorithms needed in WCDMA and OFDM receivers are overviewed and the needed computation resources are specified based on the analysis. The high-level architecture of the dual-mode receiver is also presented. A software development model is specified for the platform.
