Abstract
A system for communicating through a solid wall uses piezoelectric transducers in a multiple-input multiple-output configuration and applies crosstalk suppression. Methods of suppressing or avoiding crosstalk between parallel communication channels includes zero-forcing, eigenmode transmission, and least mean squared error processing. Orthogonal frequency division multiplexing can be used to increase transmission rates using many subchannels. Bit-loading can be used to maximize system performance.
