Methods of reduced-complexity max-log-APP processing are disclosed for use with Turbo and Turbo-like decoders. The invented methods of decoding are derived from max- log- APP processing and significantly lower the processing required for decoding convolutional codes by eliminating a portion of the calculations conventionally associated with max-log- APP processing. The disclosed embodiments provide simplified methods of metric combining based on determining the bits of an MLSE sequence with different alterative approaches. Also disclosed is an early stopping method that uses the reduced- complexity max-log-APP decoder to reduce the average number of decoding operations required by an iterative Turbo decoder.
