DIGITAL RECEIVER FOR RADIO-FREQUENCY SIGNALS
First Claim
1. A radio frequency receiver, comprising:
- a plurality of analog signal couplers, for communicating a representation of a radio frequency signal;
a respective analog to digital converter for each of said couplers, each having an output presenting a digital representation of the representation and an associated clock;
a non-blocking switch matrix, receiving the plurality of outputs and associated clocks, and producing a plurality of regenerated outputs and associated regenerated clocks under selective control of a switch matrix signal; and
a plurality of digital radio frequency signal processors, adapted to receive at least one regenerated output from the non-blocking switch matrix and associated regenerated clock.

22. A system for receiving signals, comprising:
-
a plurality of signal receivers, adapted to generate digital data directly from a received radio frequency signal substantially without frequency translation, based on a digital data clock signal defined independently of the received signal and having a sufficiently high clock rate to preserve information modulated in the received radio frequency signal, each having a respective output; and
a switch matrix adapted to receive and selectively direct the outputs of the plurality of signal receivers, and respective associated digital data clock signals, to a plurality of digital signal processors, each accepting the generated digital data at the high clock rate. - View Dependent Claims (23, 24)
