Web23 May 2008 Β· Parity check matrix finds its usefulness in the receiver side for error-detection and error-correction. According to parity-check theorem, for every generator matrix G, there exists a parity-check matrix H, that spans the null-space of G. Therefore, if c is a valid codeword, then it will be orthogonal to each row of H.
