A Software Defined Radio Implemented using the OSSIE Core Framework Deployed on a TI OMAP Processor
… a different processor architecture is described. OSSIE, an open source SCA implementation developed at Virginia Tech, was ported to the ARM processor by adding support for building OSSIE into the OpenEmbedded build system. Once the port for the OMAP starter kit was complete, it became possible to …
