cycle_search
- 本程序是用来查找LDPC parity-check matrix中的cycle的. 以次可以方便知道girth 的情况.-This program is used to find all the cycles in the parity-check matrix of the LDPC codes. By using this program we can also know the girth condition of our codes.
LDPC_simulation
- 这是一个LDPC 的matlab 仿真程序. 信道为AWGN. 调制方式为BPSK. 程序包里包含多种编码, 译码方式.-This is a box of LDPC simulation programs. The channel is AWGN channel and the modulation is BPSK. There are different encoding and decoding methods.
shift_choosing
- 这个程序 是用来为QC-LDPC 的parity check matrix 选择 shift values的. 其中 0 matrix 的shift value为-1.-this program is used to assign the shift values for parity-check matrix of the QC-LDPC codes. The shift value of the zero matrix is-1.
