It is worth emphasizing the code is not necessarily specification compliant with IEEE In particular, aspects such as puncturing, padding, and stream parsing are not implemented. The above numbers are based on 20 iterations of the BP decoder without early termination. So, typically, one should see much better performance.

Note that for speed up of simulation, it is assumed in the main file that if a given run as in info bit and noise realizations is decoded for a lower EbNo value, then it will be decoded for a higher EbNo value.

Hamid Reza Barzegar on 14 Dec Vote 0. Commented: Hamid Reza Barzegar on 14 Dec I want to know is there any implementation of mentioned with matlab or no? Answers 1.Updated 25 Feb Message encoding uses sparse LU decomposition. Bagawan Nugroho Retrieved April 14, Can you clarify that why BER is compared for the result after decoding i.

All i get is a blank plot. Please kindly help. If I want to use igenerated matrix H by makeLdpc with comm. It poster a n error message 'The las comumn n-k must be invertible in GF 2. Is there any way to make the code run faster for generating large parity check matrices? For generating a by matrix, this code will run forever! Sir can i know the algorithm used to create the H matrix in makeLdpc.

Thank you for the programs. But there some problems concerning the algorithm decodeLogDomainSimple: and specially in the calcul of the prior-likelihood simplified. Your Noise Calculation have some problem. The code rate is 0. You noise addition with signal is ok. But when you are transferring N0 to decodeLogDomain.

You may have to cross check the performance and benchmark it. If I am not mistaken, there is conflict in the results. The BER results your program for short length of LDPC codes are not reliable, unbelievable, please check your program with other's published one. Learn About Live Editor.

S view profile.A low-density parity-check LDPC code is a linear error correcting code, a method of transmitting a message over a noisy transmission channel. An LDPC is constructed using a sparse bipartite graph.

LDPC codes are capacity-approaching codes, which means that practical constructions exist that allow the noise threshold to be set very close or even arbitrarily close on the BEC to the theoretical maximum the Shannon limit for a symmetric memoryless channel.
