SYSTEMS, METHODS AND APPARATUSES FOR WIRELESS CAPACITIVE RECEPTION AND TRANSMISSION OF SIGNALS WITH DISTORTION COMPENSATION IN A CHANNEL (VARIANTS)

摘要

Disclosed is a system for wireless capacitive reception and transmission of signals with distortion compensation in a channel, including a transmitting and a receiving apparatuses, which are configured, respectively, of wirelessly transmitting and receiving signals, wherein the transmitting apparatus comprises a signal precompensator with an input for data signals which are transmitted, a signal driver with an input for prepared signals and precompensation signals, and transmitting terminals which are spaced apart and are connected to the outputs of the signal driver in such a way that corresponding electrical fields are produced. The receiving apparatus includes spaced-apart receiving terminals, which are capable of detecting the electrical fields produced by the transmitting terminals and received signals which are reproduced on the receiving terminals, and an adaptive signal corrector, the inputs of said adaptive signal correcter being connected to the receiving terminals, and which adaptive signal corrector has outputs for received data signals.
