RS码又称里所码，即Reed-solomon codes，是一种前向纠错的信道编码，对由校正过采样数据所产生的多项式有效。当接收器正确的收到足够的点后，它就可以恢复原来的多项式，即使接收到的多项式上有很多点被噪声干扰失真。-RS code, also known as the code, that is, codes Reed-solomon, is a forward error correction of the channel coding, the data generated by the correction of the sampling data is valid. When the receiver is correctly received enough points, it can restore the original polynomial, even if the received polynomial has a lot of noise distortion.
