Abstract
A system includes a first device having a first transceiver and a first device electrode pair connected to the first transceiver, and a second device having a second transceiver and a second device electrode pair connected to the second transceiver. The second device electrode pair is located relative to the first device electrode pair such that the first device electrode pair and the second device electrode pair form a capacitive network. The first transceiver and second transceiver are each configured to receive a plurality of bits, encode each bit of the plurality of bits, and DC balance and transmit each of the plurality of encoded bits over the capacitive network. Methods for use with the system are provided for encoding and transmitting data, as well as receiving and decoding the encoded data.
