I am doing a channel coding simulation and ... an n=50-block size code using 100-interation decoding takes about twenty minutes to complete (on my AMD 2.8GHz with 512MB RAM PC). An n=500-block size code using 100-iteration decoding took 1 and a half hours. An n=500-block size code using 200-iteration decoding took 3 hours plus. Now, my n=1000-block size code using 200-iteration decoding is in its 8th hour of execution... and still going on. Gosh... how long do I have to wait? This had better give me a damn good BER vs Eb/N0 graph!
I hope my supervisor sees this post. OK - no, I'd rather not. :D
