A matlab implementation of the 802.11n LDPC encoder and decoder
Note
builHG > Only needed if not usign back substitution (very slow) ldpcTxSystem > Contain the message passing decoder matlab implementation (very slow) Contain a message passing decoder C implementation [mexdecoder.c] (faster but not optimal) ldpcTxSystemFast> Contain a message passing decoder C implementation [mexfastdecoder.c] (fastest, but break the compatibility with the previous matlab code) ldpcTest > Test for ldpcTxSystem ldpcTestFast > Test for ldpcTxSystemFast
Not really useful file (SHOULD BE CONSIDERED DEPRECATED): buildHG ldpcTxSystem ldpcTest mexdecoder.c
MATLAB R2016
From this version of MATLAB (maybe also others before), MATLAB tries to start a parallel pool automatically when a parfor keywork is reached, making the flag parallelComputation unuseful.
To disable this go to unchek Preferences > Parallel computating toolbox > Automaticallly create parallel pool.
