MMSE Pre-emphasis Incorporating Spatial Diversity for Wideband Implant Communications

This study proposes a pre-emphasis technique, implemented using the minimum mean-square error (MMSE) algorithm, to incorporate spatial diversity and improve the bit error rate (BER) performance for wideband implant communications. A three-branch transmit diversity scheme is performed using a numerical human model and miniaturized antennas in simulation. Results confirm that the proposed communication system achieves a high data rate of 20 Mbps across antenna orientations spanning 0 to 180 degrees.
