  Abstract

Recently, magnetic induction (MI) communication has drawn much attention because it is less affected by environmental factors in complex environments such as underwater, underground, and pipeline channels where acoustic, optical and electromagnetic waves are not appropriate. Since the MI communication system is composed of the circuits with coil antennas, the bandwidth of this system is narrow, and thus enhancement in spectral efficiency of the MI communication system becomes a critical issue. Orthogonal frequency division multiplexing (OFDM) is effective to increase the spectral efficiency, and we propose in this paper an implementation of an OFDM-based magnetic induction communication system through a universal software defined radio peripheral and GNU radio. The performance of the implemented system is evaluated by extensive experiments in the air.
