Abstract
A communication quality estimating device estimates an error rate of a signal with FEC capable of correcting K errors. The device obtains a frequency measurement value that indicates a frequency at which a codeword including m errors is received. The device determines a transition probability and a continuation probability included in each of a plurality of formulae, such that a frequency calculation value that is calculated using the plurality of formulae and indicates a frequency at which a codeword including m errors is received is brought close to the frequency measurement value. The device calculates a frequency at which a codeword including more than K errors is received, by using the plurality of formulae each with the determined transition probability and the determined continuation probability. The device estimates after-FEC error rate based on a result of the calculation.
