Abstract
A transmitter and a receiver for transmitting and receiving data via a power supply line comprise a local signal port for respectively receiving and transmitting a serial bit stream and a power line connection port for respectively transmitting a radio frequency signal and receiving the radio frequency signal via the power supply line. The transmitter comprises a modulator unit adapted for encoding the serial bit stream into a baseband signal and generating the radio frequency signal by mixing the baseband signal with a carrier wave so as to redundantly convey the at least one baseband signal in at least four spectral sidebands of the carrier wave. The receiver comprises a demodulator unit adapted for detecting the at least four spectral sidebands of the carrier wave in the radio frequency signal, isolating a baseband signal from the at least four spectral sidebands and decoding the baseband signal into the serial bit stream.
