| Abstract(in English) | In this paper, we propose an improvement method of transmission characteristics in acoustic OFDM using microphone array. Recently, acoustic OFDM (Orthogonal Frequency Division Mutiplex), which uses audible sound wave as an information transmission medium, has been studied. The acoustic communication embeds information in audio data in advance and transmits it through loudspeakers, and receives it by the microphone. In real environments using acoustic OFDM, the reverberation and the noise in the environment have influence on the transmission characteristic. We therefore propose an improvement method of the transmission characteristic using microphone array in order to solve the above problem and demonstrate the efficiency of the proposed method through some transmission experiments. |
