摘要
A device receives signals over a communication medium and uses a low density parity check decoder to decode data in the signals. A number of unsatisfied parity checks are counted prior to a first decoding iteration of the low density parity check decoder on a basis of log likelihood ratios computed from the signals. An operational characteristic of the low density parity check decoder is computed based on an accumulated number of unsatisfied parity checks.
