Abstract
A multi-band synthesizer generates a multi-band signal for transmission. The multi-band signal comprises a plurality of band signals each comprising one or more channel signals. The channel signals to be included in a particular band signal are specified in control signals, allowing the channels included in a band to be easily changed.
Claims20
A multi-band synthesizer for a multi-band transmission system, the multi-band synthesizer comprising:
- a plurality of intermediate frequency (IF) channel inputs for receiving a plurality of IF channel streams;
- and
- a plurality of band synthesizers, each coupled to the plurality of IF channel inputs, each of the plurality of band synthesizers comprising a signal combiner for selectively combining a subset of the plurality of IF channel streams received at the plurality of IF channel inputs into a respective band signal according to a band membership control signal indicating one or more of the plurality of IF channel streams to combine into the band signal.
A multi-band transmission system comprising:
- a channel tuner for frequency shifting a plurality of channel streams according to at least one band membership control signal indicating one or more of the channel streams to be combined together into respective band signals, the channel tuner outputting a plurality of intermediate frequency (IF) channel streams each corresponding to a respective channel stream;
- and
- a multi-band synthesizer for generating a plurality of band signals, the multi-band synthesizer comprising:
- a plurality of band synthesizers, each comprising a signal combiner for selectively combining a subset of the plurality of IF channel streams output from the channel tuner into a respective band signal according to the at least one band membership control signal provided to the band synthesizer indicating one or more of the plurality of IF channel streams to combine into the band signal.
1 more element
A method for use in a multi-band transmission system, the method comprising:
- receiving at least one band member control signal indicating one or more of the plurality of intermediate frequency (IF) channel streams to be combined together into respective ones of a plurality of band signals;
- and
- combining the plurality of IF channel streams into the plurality of band signals according to the at least one band member control signal.
