Throughput ● Highest number in Ng et al : 29.1 Mbps ● Highest number in 802.16 spec : 134 Mbps ● Maximum empirical achieved by optimal design : 393 Mbps 24
Conclusions ● <strong>Reed</strong> <strong>Solomon</strong> decoder parameterized by the primitive polynomial. ● Meets specification for 802.16, but easily adaptable to other applications, such as CD. ● Exceeds 802.16 throughput requirement by a factor of 10. ● Designed for integration with the OFDM framework. ● Developed generalized GF arithmetic functions for Bluespec. 25
