Abstract
A signal receiving apparatus provides a flexible architecture for single or multiple channel reception capability. According to an exemplary embodiment, the signal receiving apparatus includes a front-end processor and one or more channel recovery elements. The front-end processor includes an A/D converter, a demultiplexer, and one or more filters. The A/D converter receives analog RF signals and converts the analog RF signals to digital RF signals. The demultiplexer Decimates the digital RF signals to generate decimated RF signals. The one or more filters filter the decimated RF signals to generate filtered RF signals. The one or more channel recovery elements process the filtered RF signals to provide baseband signals corresponding to one or more frequency channels.
Claims21
A signal receiving apparatus, comprising:
- front-end processing means including:
- analog-to-digital converting means for receiving an analog RF signal having a plurality of channels and converting said analog RF signal to a digital RF signal;
- means for reducing sampling rate of said digital RF signal to generate a plurality of decimated RF signals;
- and
- means for filtering said plurality of decimated RF signals to generate a plurality of filtered RF signals;
- and
- channel recovering means for processing said plurality of filtered RF signals to provide at least one baseband signal, each of said at least one baseband signal corresponding to a respective channel.
A method for operating a signal receiving apparatus, comprising:
- receiving an analog RF signal;
- converting said analog RF signal to a digital RF signal;
- reducing the sampling rate of said digital RF signal to generate a plurality of decimated RF signals;
- filtering said plurality of decimated RF signals to generate a plurality of filtered RF signals;
- and
- processing said plurality of filtered RF signals to provide at least one baseband signal each of said at least one baseband signal corresponding to a respective channel.
A signal receiving apparatus, comprising:
- a front-end processor including:
- an analog-to-digital converter operative to receive an analog RF signal and convert said analog RF signal to a digital RF signal;
- a demultiplexer operative to decimate said digital RF signal to generate a plurality of decimated RF signals;
- and
- one or more filters operative to filter said plurality of decimated RF signals to generate a plurality of filtered RF signals;
- and
- one or more channel recovery elements operative to process said plurality of filtered RF signals to provide at least one baseband signal corresponding to a respective channel.
