LLR COMPUTATION DEVICE AND ERROR CORRECTION DECODING DEVICE

摘要

A two-pair reference point pair setting unit (101) sets two reference point pairs, selecting two send symbol points for LLR computation, said send symbol points having a bit value of 0, and selecting two send symbol points for LLR computation, said send symbol points having a bit value of 1. An LLR computation unit (113) weights and adds together two LLRs computed for each of the two reference point pairs, and computes the LLR for each of the two reference point pairs, as the value obtained by adding a correction term to the LLR sum, said correction term being 0 in some cases.
