Hi
I checked it, it's work very good
 

matlab codes for ldpc

Here are some codes I developed for LDPC. All of them are for hard decision bit-flipping algorithm.

Hope this helps.

I will be updating the codes from time to time.

belief propagation matlab

so many, which is sufficient for a new comer of this field
 

belief propagation algorithm ldpc software

give me one best source for belief propogation decoding for LDPC.
Is bit-flipping better or belief propogation.
 
matlab ldpc

hi i am also working on belief propagation algorithm for ldpc codes, can anyone help me to find some sample codes about belief propagation preferably written on matlab?

Thanks
 

matlab bit flipping

hello, does any body had more of software
 

matlab code for ldpc

Could anyone help me find some software that is about Finite-Geometries based LDPC codes? I've some confusion in the coding algorim.
 
belief propagation in matlab

Most of the matlab codes fir LDPC on the website are designed for Gaussian channels.


I am confused if it is possible to use same code over some fading channels as well ?

If no, than what should be changed so that the code for AWGN can be used over fading channels like Rayleigh.

please suggest ..
 

belief propagation matlab program

yes ofcourse
change the noise equation in your code for fading channle

wish you good luck

LDPC software (Matlab)

can anybody help me out here...

we can generate a Fixed size LDPC matrix using matlab very easily e.g 32400*64800.. but what if i want to change the dim of my Matrix.. for say 100*200.. anybody any idea.

sparse matrix helps a bit, but Matlab gives an errror saying that it has to b something like defined over GF(2)....
driving me crazy... anyone give me the idea and code or anything......:cry::cry::cry:

thanks always..
 
LDPC software (Matlab)

Elo..am a student too.. I am doing my final year project on evaluation of GSM system using LDPC codes.Am not getting a graph of waterfall for the BER !!!What can you suggest me ??
ThaNks
 

Re: flipping bits in matlab

Please reply me quickly.. i need to submit some graphs and readings to continue my project.
Thanks

Which one should i run first ???
Because when running the Encode.m, am getting invalid and garbage values for BER etc etc ... and its asking me some inputs which i myself don;t know what are the variables for .. there are no comments.
Am getting a few problems with that can you please help me ...
There are undefined variables in other mfiles too...
Thanks in advance
