Abstract
Systems, methods, and apparatus are provided for improving the iterative decoding performance of a decoder, for example, as used in a wireless communications receiver or in a data retrieval unit. A decoding technique may receive and process a set of channel samples using an iterative decoder. If the iterative decoder output indicates a decoding failure, noise samples may foe combined with the received channel samples to create biased channel samples. Noise sample may be generated using a pseudo-random noise generator and/or by using signals already present in the communications receiver or data retrieval unit. The biased channel samples may be provided to the iterative decoder and the iterative decoder may re-run using the biased channel samples.
