Executive Summary

Software Radio (SR) is an emerging paradigm of the wireless communication system design due to its flexibility and adaptability. However, the implementation of SR platform is always challenging, especially for high date rate transmission such as up to 1Gbps. Although General-Purpose Processor(GPP) based SR platform can take full advantages of Software Radio, the performance is often limited due to the lack of real-time processing capacity for high-throughput radio systems, especially for high-throughput channel decoding. Therefore, Hardware Accelerating Units(HAU) are usually also involved in the SR platform, such as Field Programmable Gate Arrays(FPGAs) and embedded Digital Signal Processors(DSPs).
