The Reed-Solomon error correction code is a powerful error correction tool for data transmission channels, providing improved message error rate at the cost of reduced channel throughput. A reduced length version of a basic Reed-Solomon code can be constructed by truncating the code and assuming the truncated symbols are all zero. A truncated code can be used to optimize accuracy and efficiency of a data transmission channel by matching the code's length to the system's requirements. As the code's length is reduced (e.g., a (63, 51) Reed-Solomon basic code might be truncated to a (31, 19) length), message error rate improves but channel throughput is reduced.
