Critical point for maximum likelihood decoding of linear block codes
M.P.C. Fossorier · IEEE Communications Letters · 2005
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.
