Abstract:
Software-defined radios (SDRs) present a promising approach to face the demands of today’s fast evolving environment of wireless communication standards. Ever increasing requirements in terms of performance and flexibility call for programmable, highperformance signal processing platforms. This thesis contributes to the SDR research domain, addressing the implementation of a 2 x 2 MIMO-OFDM receiver on an SDR platform. Appropriate receiver algorithms are evaluated with special regard to the associated computational complexity. The use of low-complexity algorithms is imperative to spare the limited processing resources available on the SDR platform. The platform consists of two application specific processors, each tailored to the computational needs of the associated digital signal processing kernels. The first processor performs the per stream MIMOOFDM processing. The second processor handles the MIMO detection. The layout of the proposed processors in 0.18 μm CMOS technology is presented and provides reference for silicon area

and power consumption.
