Transmitter and receiver for a communication system, communication system and method of transmitting information
View Patent ↗Embodiments of the present invention provide a transmitter ( 100 ) for a communication system comprising a modulator ( 110 ) configured to generate a transmit signal ( 120 ) while modulating information on a plurality of sub-bands ( 120 a, . . . , 120 d ), wherein at least two of the sub-bands ( 120 a, . . . , 120 d ) have a different bandwidth.
1 . A transmitter for a communication system, comprising:
a modulator configured to generate a transmit signal while modulating information on a plurality of sub-bands, wherein at least two of the sub-bands have a different bandwidth and the amount of information modulated on each sub-band is identical.
2 . The transmitter of claim 1 , wherein a bandwidth of the plurality of sub-bands increases monotonically with the center frequency of the sub-bands.
3 . The transmitter of claim 1 , further comprising:
an output for the transmit signal, which is configured to be coupled to a wireline medium.
4 . A communication system for a motor vehicle, comprising:
a data bus;
a first node with a first transmitter of claim 1 coupled to the data bus for transmitting information via the data bus; and
at least one second node comprising a second transmitter of claim 1 , which is coupled to the data bus for transmitting information via the data bus.
5 . The communication system of claim 4 , wherein the first node and the second node are coupled to the data bus in a daisy chain arrangement.
6 . A motor vehicle with a communication system of claim 4 .
7 . A receiver for a communication system, comprising:
a demodulator configured to demodulate an input signal with a plurality of sub-bands of different width and to reconstruct the information transmitted in a sub-band such that the amount of information in each sub-band is identical.
8 . The receiver of claim 7 , further comprising:
an analog-to-digital converter configured to digitize a received signal and to provide the same as a digital input signal for the demodulator.
9 . A method of transmitting information, comprising:
modulating information to a first sub-band;
modulating information to a second sub-band, wherein the first sub-band and the second sub-band have a different bandwidth and the amount of information modulated to the first sub-band and to the second sub-band is identical; and
transmitting a transmit signal comprising the first sub-band and the second sub-band.
