Abstract
A method includes receiving an input via a processor of the computing device. The input corresponds to data to be transmitted. The method further includes encoding the data to generate spreading codes corresponding at least in part to the data. The method further includes 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, and transmitting the transmit signal via an electrode capacitively coupled to a physical body. The transmit signal is transmitted from the electrode through the physical body.
