1. A method implemented by a computing device, the method comprising:
receiving an input via a processor of the computing device, wherein the input includes data to be transmitted;
encoding the data to generate spreading codes corresponding at least in part to the data;
mapping the spreading codes to one or more frequency subcarriers of a plurality of frequency subcarriers;
generating a transmit signal based at least in part on the one or more frequency subcarriers;
determining one or more transmitter electrodes, from a plurality of electrodes of the computing device, that maximize a differential capacitive coupling to a physical body;
selecting the determined one or more transmitter electrodes to be transmission electrodes for transmitting the transmit signal to the physical body;
amplifying the transmit signal for transmission to the selected one or more transmitter electrodes of the computing device; and
transmitting the amplified transmit signal via the selected one or more transmitter electrodes capacitively coupled to the physical body, the transmit signal being transmitted from the selected one or more transmitter electrodes through the physical body.
