c#中对文件的操作小结-the paper"s operation Summary

In this paper, we present two encoding methods for block-circulant LDPC codes. The first is an iterative encoding method based on the erasure decoding algorithm, and the computations required are well organized due to the blockcirculant structure of the parity check matrix.
