Dataset related to "Girth analysis and design of periodically time-varying SC-LDPC codes"

This archive contains the parity-check matrices of the codes considered in the paper "Girth analysis and design of periodically time-varying SC-LDPC codes". Two representations are given: the exponent matrix in time-varying form and the transposed syndrome former matrix in the "alist" format, described in http://www.inference.org.uk/mackay/codes/alist.html. The archive also contains the following MATLAB support functions:<br> <br> - "expTIfromexpTV.m" returns the exponent matrix in time-invariant form, given the exponent matrix in time-varying form<br> - "expTVfromexpTI.m" returns the exponent matrix in time-varying form, given the exponent matrix in time-invariant form<br> - "alist2sparse.m" returns a sparse binary matrix variable, given a string containing the name of the alist format file<br> - "sparse2alist.m" writes the alist format file for the input sparse binary matrix, with file name specified as second input<br>
