| 摘要 |
The present invention relates to a transmitter (1) and a receiver (6) for transmitting and receiving data via a power supply line (4). The transmitter (1) and the receiver (6) comprise a local signal port (2, 7) for respectively receiving and transmitting a serial bit stream and a power line connection port (3, 8) for respectively transmitting a radio frequency signal and receiving the radio frequency signal via the power supply line (4). The transmitter (1) comprises a modulator unit (5) 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 (6) comprises a demodulator unit (9) 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. |
