چکیده
|
In this paper, an explicit class of affine permutation matrix low-density parity-check (apm-ldpc) codes is presented. this class is constructed based on the array parity-check matrix by using two affine maps f(x) = x-1 and g(x) = 2x-1 on zm, where m is an odd prime number, with girth 6 and flexible row (column)- weights. simulation results justify well performance, minimum distances and cycle distribution of these codes in comparison of the array-qc ldpc, structured qc-ldpc and apm-ldpc codes.
