Acoustic communication has broad utility for near field, device-to-device communication, since it utilizes the standard equipment; speaker and microphone. In this paper, a simple acoustic modem that enables communication using orthogonal frequency division multiplexing (OFDM) is focused on. In near-field acoustic communication, the effect of the environmental noise cannot be negligible. To achieve reliable communication, the modem is designed to use antenna diversity which utilizes multiple microphones. To confirm the effectiveness of the antenna diversity technique, simulation of acoustic communication using real channel data is performed. As a result, it was confirmed that the modem with the antenna diversity technique could achieve lower bit error rate (BER) than that without antenna diversity.
