Abstract

Presence of echo is one of the challenges when using ultrasonic for transmitting data through the steel. The model of multipath channel in the ultrasonic through-steel communication system is described and the method of echo cancellation is analyzed in this paper. This method applies a pre-distortion filter to mitigate the effects of echo in order to decrease the complexity of the receiver. The method of echo cancellation is simulated in MATLAB, and simulation results show that echo is suppressed greatly comparable to the line-of-sight received signal in the ultrasonic communication system. The results show the validity.
