PROBLEM TO BE SOLVED: To enable a modem to perform synchronization processing and BER (Bit Error Rate) measurement, without performing synchronization processing according to a conventional technique such as guard interval signal correlation, by providing, to an OFDM modem section, a simplified synchronization processing function and BER measuring function for the BER measurement different from the prior arts, in a BER measuring apparatus. SOLUTION: The BER measuring apparatus comprises: a fixed-cycle signal output means (S12) for outputting a fixed-cycle signal when carrying out synchronization processing; synchronization processing means (S13-S14) for generating a synchronizing signal based on the fixed-cycle signal outputted from the fixed-cycle signal output means; an OFDM modulation means (S16) for outputting an OFDM modulation signal when carrying out the BER measurement; an OFDM demodulation means which inputs (T3) the OFDM modulation signal outputted from the OFDM modulation means to perform OFDM demodulation using the synchronizing signal; and BER measuring means (S18-S19) for performing the BER measurement based on an OFDM demodulation signal on which OFDM demodulation has been performed by the OFDM demodulation means.
