EVENT CLEANUP PROCESSING FOR IMPROVING THE PERFORMANCE OF SEQUENCE BASED DECODERS

摘要

The invention relates to improving the performance of sequence-based soft- output decoders using event cleanup processing, wherein combinations of potential error events are evaluated using an error detection code (EDC) to select events that produce a modified set of decisions that has no EDC detectable errors. the event cleanup method and associated event cleanup decoder enable to significantly improve the error rate performance of sequence based decoders and/or significantly improve decoding efficiency compared to other known error cleanup methods.
