Software Defined Radio Platform for Cognitive Radio: Design and Hierarchical Management

Abstract : Cognitive radio (CR) and/or Software Defined Radio (SDR) inherently require multiband and multi-standard wireless circuit. A SDR is a communications device whose functionality is defined in software. Defining the radio behaviour in software removes the need for hardware alterations during a technology upgrade. A promised open architecture platform for SDR is proposed in this chapter. The platform consists of reconfigurable and reprogrammable hardware platform which provide different standards with a common platform, the SDR software framework which control and manage the whole systems, and the protocol processing software modules which is built on reusable protocol libraries. The main idea here is to have a very flexible platform that enables us to test the validity of the following design approaches: FPGA dynamic partial reconfiguration techniques, parameterization design approach using common operators, hierarchical distributed reconfiguration management.
