ASIP-based universal demapper for multiwireless standards

Résumé

The emergence of diverse wireless standards, employed in various transmission environments, is leading towards evolution of flexible radio platforms. In this letter we are presenting the first universal ASIP-based flexible and scalable demapper. The presented architecture provides the flexibility ranging from low complexity QPSK Gray mapped constellations to a high complexity 256-QAM rotated constellations in turbo demodulation framework. The proposed architecture provides the liberty to use this demapper both in iterative and non-iterative receivers. Synthesis results demonstrate that the throughput of the ASIP reach up to 606 Mega LLRS per second for 16-QAM Gray mapped constellation.
