Abstract
Equalization circuits and methods are implemented for a variety of applications. According to one such application, a transmitting device wirelessly communicates using an antenna. The device has a transmission circuit that is configured and arranged to transmit a first wireless signal using magnetic coupling between the antenna and a remote device, the coupling occurring over a wireless medium. A receiver circuit of the transmitting device is configured and arranged to receive a second wireless signal that is from the antenna and that represents the first wireless signal as modified by the coupling occurring over the wireless medium. An error circuit of the device is configured and arranged to generate an error signal by comparing the first wireless signal to the second wireless signal. An equalizer circuit of the device is configured and arranged to pre-code the first wireless signal with coding that compensates for inter-symbol interference by compensating for the error signal.
