Abstract

We report on the implementation of a software defined radio (SDR) based on state-of-the-art digital signal processors (DSPs). While time critical operations are executed on specialised transmit and receive processors with a fixed block structure, the baseband processing is performed on highly flexible DSPs. We comment on the SDR building blocks, and the software implemented on this test-bed including blind synchronisation, equalisation, and carrier recovery for differentially encoded quadrature amplitude modulation. The functionality has been tested by audio transmission. We conclude with an analysis of capabilities and limitations of the implemented SDR structure
