说明：  RS码(Reed—Solomon码)是多进制BCH码，也是目前最有效、应用最广泛的差错控制编码。它具有很强的纠错能力，随机错误、突发错误都能纠正，特别是在短的和中等码长其性能接近于理论值。再加上构造方便，编码简单，设备不复杂，因此在实时性要求较高的数字通信及深空通信方面有广泛应用
(RS code ( Reed- Solomon code ) is a multiple of BCH code, is currently the most effective, the most widely used error control coding. It has a strong error correction ability, random error, burst error can be corrected, especially on short and medium length code performance close to the theoretical value. Plus convenient construction, simple coding, equipment is not complex, so the real-time digital communication and deep space communication is widely used )
