Study on encoding of RS codes with RS decoders

The encoding feasibility with Reed-Solomon decoders is discussed meanwhile the performance of the suggested coding method is compared to that with conventional coding methods in terms of algorithm operation speed, complexity and memory occupancy. Theoretical analyses and experimental results show that the initialization with the suggested encoding method proceeds much faster than that with the conventional encoding methods as the error correction capability gets stronger, and the encoding process itself with the suggested encoding method almost keeps as fast as that with the conventional encoding methods at a higher code rate. Thus, the encoding method using RS decoders as encoders is of rather high importance in practical communications equipments and is applicable for the case in which different RS encoders are required so as to meet the needs of dynamic channel characteristics and the requirements of powerful error correction.
