Abstract:
1. An input bit error ratio estimating method, comprising: a computing step of computing a decoding bit inversion ratio and a post-decoding residual error detection ratio based on a signal for monitoring a decoding result of decoding processing of an error correction code; a condition determining step of determining which of a plurality of conditions set in advance to be narrowed down to one has been established based on the post-decoding residual error detection ratio; an input BER estimating step of selecting one of a plurality of processing procedures for estimating an input BER, based on one of the plurality of conditions that is determined in the condition determining step as one that has been established, and executing the selected one of the plurality of processing procedures; and an estimation result outputting step of outputting a result of the one of the plurality of processing procedures executed in the input BER estimating step, wherein the plurality of conditions in the condition determining step comprise the following Conditions A to C: wherein the input BER estimating step comprises:
