Implementing fast and simple FEC for ultra high frequency radio

This paper describes the implementation of a fast information encoder and decoder for UHF radio considering the trade-off of speed of operation and storage space. (24, 12, 8) Golay code was implemented on an 8051 core based 8-bit microcontroller with a speed of around 60 MHz. The different available techniques to encode and decode Golay codes are discussed. A comparative study of the implementation aspects of different techniques are presented and a final solution which gives the best trade-off of speed of operation and storage space is provided.
