Abstract
Systems and methods for more efficiently decoding convolutional LDPC encoded communication signals are described. A decoder circuit iteratively determines the values of received data bits and confidence values corresponding to the determined data bit values. Using the confidence values and one or both of check fail counters and log likelihood ratio (LLR) sign changes, the decoder circuit can determine that a desired level of confidence has been satisfied and can subsequently terminate decoding operations to save power.
