ABSTRACT
Polar codes gained large interest in the last years since they are the first channel codes that are proven to achieve channel capacity. Due to this property, Polar codes were recently adopted for the 5G standard. We present an industrial framework for the generation of Polar code decoders for highest data throughput. The framework automatically generates VHDL models ready for synthesis, placement and routing and corresponding simulation models to assess the communications performance. This framework enables Polar code decoder IP providers to give fast feedback to customers on communications and implementation performance. We demonstrate that this framework outperforms existing manually optimized decoders especially in terms of energy efficiency.
