摘要： A channel detector has a belief propagation detector, a causal and anti-causal channel output module, and a noise prediction module. The belief propagation detector is coupled to a channel and is adapted to receive a channel output. The belief propagation detector is adapted to generate tentative bit decisions based in part on the channel output. The causal and anti-causal channel output module is coupled to the belief propagation detector and is adapted to generate causal and anti-causal channel outputs based on the tentative bit decisions. The noise prediction module is coupled to the causal and anti-causal channel output module and is adapted to predict noise samples based on a difference between the channel output and the causal and anti-causal channel outputs. The noise prediction module is adapted to whiten the channel output with the predicted noise samples and to return the whitened channel output to the belief propagation detector to generate new tentative bit decisions.
