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.
