Patent ID: 8867674

Claim:
A receiver for a multi-channel communication system, comprising: a down-converter device configured to down-convert a plurality of analog signals from the multi-channel communication system to a plurality of baseband signals; an analog-to-digital converter (ADC) configured to convert the plurality of baseband signals to a plurality of digital signals; and a digital channel selection device coupled to the ADC, wherein the digital channel selection device comprises: a down mixer configured to tune the plurality of digital signals to a first intermediate frequency (IF) to generate a down-mixed representation of the plurality of digital signals; an up-mixer configured to tune the plurality of digital signals to a second IF to generate an up-mixed representation of the plurality of digital signals; and a control device configured to select one of the plurality of digital signals, the up-mixed representation of the plurality of digital signals, or the down-mixed representation of the plurality of digital signals based on which representation of the plurality of digital signals is closest to a direct current (DC) frequency for further processing to tune to a channel of interest.
