Parity bitParity check matrix for single bit error correcting code based on algebraic coding theory can be generated from the parity bit vectors by an efficient algorithm supported with examples. The novelty of this algorithm is the simplicity in its implementation.D. Roy CHOUDHURY...
通俗易懂讲通 奇偶校验 (Parity Check) 和 汉明码 (海明码、Hamming Code) 奇偶校验(Parity check) 奇偶校验是一种添加一个奇偶位用来指示之前的数据中包含有奇数还是偶数个1的检验方式 偶校验 编码过程: 当实际数据中“1”的个数为偶数的时候,校验位是“0”,反之校验位是“1”,换句话说,数据位(N位)和 ...
The H-matrix in (6.8) is known as the parity-check matrix. We can easily verify that: (6.9)GHT=IkPPIn-k=P+P=0, meaning that the parity-check matrix of an (n, k) linear block code H is a matrix of rank n − k and dimensions (n − k) × n whose null-space is k-...

In this Letter, a new parity-check-concatenated (PCC) polar code construction that considers the number of minimum Hamming weight (MHW) codewords is proposed. The parity bits to reduce the number of MHW codewords as much as possible is successively constructed. The proposed construction can redu...

A method for improving the performance of sparse-matrix based parity check codes is proposed, based on insight gained from methods of statistical physics. The advantages of this approach are demonstrated on an existing encoding/decoding paradigm suggested by Sourlas. We also discuss the application ...

For each code, a parity-check matrix, H, is defined; in order to be a valid one, for each code word, x, it must satisfy the parity-check constraint (modulo-2 operations), Hx=0. Take as an example the case of k=3 and N=6. The code comprises 23 (2k in general) code words,...
