Critical Point for Maximum Likelihood Decoding of Linear Block Codes
arXiv:cs/0504032 · doi:10.1109/LCOMM.2005.1506713
Abstract
In this letter, the SNR value at which the error performance curve of a soft decision maximum likelihood decoder reaches the slope corresponding to the code minimum distance is determined for a random code. Based on this value, referred to as the critical point, new insight about soft bounded distance decoding of random-like codes (and particularly Reed-Solomon codes) is provided.
