Hi, i have to design a parallel LDPC decoder with stochastic decoding capability.
The principle is to convert the channel LLR values into stochastic bit stream, where the probability of 1s in the output bit stream is equal to input LLR value.
So far i know that to do so, we need a comparator which compares a normally distributed random number R with input N, if R<N the output is 0 else 1.
Kindly someone help me out, in writing a vhdl code for that, any matlab/C routine will also be useful for me.
Regards.
