To test the LDPC encoding and decoding functions, run the following function under matlab
test_all_ldpc_cases
The LDPC decoding function decLDPC_layered.m is from Simulator for LDPC decoding in IEEE 802.11n and the author is Christoph Studer. I made some small modifications on it to accelerate its execution.
The LDPC decoding function ldpc_decode.m is from https://github.com/willemolding/FastPythonLDPC .
The two included excel files are from 3gpp. The matlab codes other than decLDPC_layered.m and ldpc_decode.m follow the MIT license.
