| Abstract(in English) | With OFDM, which is a kind of multi carrier systems, it is possible to perform a differential coding/differential detection in the direction of time axis or frequency axis depending on the environment of transmission with the adoption of DQPSK as a method of subcarrier modulation. This paper proposes an approximate derivation method of average bit error rate in DQPSK/OFDM Systems as mentioned above over frequency non-selective Nakagami-Rice fading and Rayleigh fading channels. Since the result with this approximate derivation method coincides with that of the computer simulation, even when the system parameters such as Doppler frequency and so on are varied, hence, the validity with this method is confirmed. |
