DELAYED DECISION FEEDBACK SEQUENCE ESTIMATOR AND METHOD

摘要

PROBLEM TO BE SOLVED: To provide a delayed decision feedback sequence estimator (DDFSE) for increasing processing speed without relying on processing speed of a DDFSE computing unit. SOLUTION: The delayed decision feedback sequence estimator (DDFSE), whose received data symbol sequence is divided into a plurality of blocks of the same length mutually, includes a group of DDFSE computing units 104 equal in number to a length of each block. The group of DDFSE computing units are connected in a pipeline configuration and includes: a delayed decision feedback sequence estimator main unit 101 to execute delayed decision feedback sequence estimation of the blocks in parallel; and an edge effect detection and correction circuit 102 that detects an edge effect due to processing the delayed decision feedback sequence estimation of the separated block and corrects a relevant bit error.
