A high data rate wireless transmission scheme, utilizing the Medical Implant Communications Service (MICS) band for implantable medical devices (IMD) is proposed. An orthogonal frequency division multiplexing (OFDM)-based multicarrier scheme is used to overcome the data rate limitation caused by the narrow bandwidth. By optimizing subcarrier allocation, inverse fast Fourier transform (IFFT) architecture and sidelobe suppression techniques, the proposed scheme utilizes multiple MICS channels simultaneously, satisfying the MICS mask specification. Simulation results show that this scheme can support a maximum data rate of 4.86 Mbps, which is more than ten times faster than the existing system.
