PURPOSE: To regenerate reception data and a burst reception signal without degrading the bit error rate characteristic of the reception signal by providing an MLSE equalizer capable of high-speed processing. CONSTITUTION: A replica generation part 1, an error calculation part 2, a branch metric part 3, an addition, comparison, and selection processing part 4, an impulse response operation part 2, and a path memory part 6 have independent computing elements, and an impulse response memory part 7 is inserted to simultaneously execute the write of the operation result from the impulse response operation part 5 and the read of the operation result from the impulse response operation part 5 to a replica generation part 1. A pass metric memory part is provided to simultaneously execute the read of the pass metric at the preceding time and the write of the selected pass metric at the present time selected by the addition, comparison, and selection processing part 4. |
