This repo exists solely for anyone interested in creating and using the LDPC generator matricies outlined in the IRIG 106 Telemetry Standards pdf file. LDPC matricies are commonly stored in the alist file format. For example, GNURadio LDPC encoders and decoders utilize this file format. Therefore, part of the script is a function for writing these generator matricies to an alist file. For convenience sake, the six alist files for the combinations of k=1024,4096 and r=1/2,3/4,4/5 exist in the alist folder for anyone who just wants to download these and plug them into an LDPC encoder or decoder.
