#!/bin/sh# Example of how an LDPC code can be encoded using using sparse,# dense, and mixed representations of the generator matrix. The dense# and mixed representations are based on the same set of message bits# as the sparse method with minprod heuristic. This allows the correctness # of these methods to be checked by verifying that they all produce the same # result when encoding random messages. The results are also checked by # 'verify'.## A (400,200) LDPC code with 3 checks per bit is used for the test.set -e # Stop if an error occursset -v # Echo commands as they are readmake-ldpc ex-ldpc-encode.pchk 200 400 1 evenboth 3 make-gen ex-ldpc-encode.pchk ex-ldpc-encode.genf sparse firstmake-gen ex-ldpc-encode.pchk ex-ldpc-encode.genc sparse mincolmake-gen ex-ldpc-encode.pchk ex-ldpc-encode.genp sparse minprodmake-gen ex-ldpc-encode.pchk ex-ldpc-encode.gend dense ex-ldpc-encode.genpmake-gen ex-ldpc-encode.pchk ex-ldpc-encode.genm mixed ex-ldpc-encode.genprand-src ex-ldpc-encode.src 1 200x10encode ex-ldpc-encode.pchk ex-ldpc-encode.genf ex-ldpc-encode.src \ ex-ldpc-encode.encfencode ex-ldpc-encode.pchk ex-ldpc-encode.genc ex-ldpc-encode.src \ ex-ldpc-encode.enccencode ex-ldpc-encode.pchk ex-ldpc-encode.genp ex-ldpc-encode.src \ ex-ldpc-encode.encpencode ex-ldpc-encode.pchk ex-ldpc-encode.gend ex-ldpc-encode.src \ ex-ldpc-encode.encdencode ex-ldpc-encode.pchk ex-ldpc-encode.genm ex-ldpc-encode.src \ ex-ldpc-encode.encmcmp ex-ldpc-encode.encp ex-ldpc-encode.encdcmp ex-ldpc-encode.encp ex-ldpc-encode.encmverify ex-ldpc-encode.pchk ex-ldpc-encode.encf ex-ldpc-encode.genf \ ex-ldpc-encode.srcverify ex-ldpc-encode.pchk ex-ldpc-encode.encc ex-ldpc-encode.genc \ ex-ldpc-encode.srcverify ex-ldpc-encode.pchk ex-ldpc-encode.encp ex-ldpc-encode.genp \ ex-ldpc-encode.src
