Software radio approach for re-configurable multi-standard radios

Next generation wireless systems will lead to an integration of existing networks, forming a heterogeneous network. Re-configurable systems will be the enabling technology sharing hardware resources for different purposes. This paper highlights the requirements of a reconfigurable multi-standard terminal from the physical-layer point of view. A re-configurable architecture consisting of algorithm domain specific accelerators, allowing autonomous complex digital signal processing without interference from a microprocessor, is explained. Performance comparison numbers with latest digital signal processors shows the effectiveness of the proposed architecture.
