Abstract
This paper presents an adaptive equalizer design for high-rate ultrasonic communication through solid channels. Ultrasonic communication through solid channels is prone to multipath effects, dispersion, refractions, and reverberations. These effects cause severe intersymbol interference (ISI), resulting in a high Bit Error Rate (BER) and overall deterioration of communication performance. Thus, an adaptive decision feedback equalizer (DFE) based on the fast Kalman filter algorithm is used for the equalizer design. The Kalman filter algorithm has fast convergence and good tracking ability, which is essential to reverse the distortion incurred by the ultrasonic solid channel. The performance of the proposed equalizer design is examined using simulated data to train and evaluate the efficiency of the algorithm. Simulation results confirm that adaptive equalizer improves bit rate and lowers BER.
