1. A radio-frequency (RF) body-coupled communications (BCC) transceiver (TRX) configured to function as a hybrid orthogonal frequency-division multiplexing (H-OFDM) TRX and comprising:
- an RF BCC transmitter, comprising;
a baseband phase-shift keying (BPSK) modulator and an inverse fast Fourier transform (IFFT) processing block configured to process transmit (TX) data to provide a baseband TX signal; and
a frequency hopping (FH) and frequency shift keying (FSK) RF modulator configured to RF modulate the baseband TX signal to provide an RF TX signal; and
an RF BCC receiver;
wherein the RF BCC transmitter is configured to transmit the RF TX signal to the RF BCC receiver via a body area network (BAN) of a human body.
