<p>A signal receiving apparatus (100) provides a flexible architecture for single or multiple channel reception capability. According to an exemplary embodiment, the signal receiving apparatus (100) includes a front-end processor (20) and one or more channel recovery elements (40 and/or 60). The front-end processor (20) includes an A/D converter (10), a demultiplexer (12), and one or more filters (16, 18). The A/D converter (10) receives analog RF signals and converts the analog RF signals to digital RF signals. The demultiplexer (12) decimates the digital RF signals to generate decimated RF signals. The one or more filters (16, 18) filter the decimated RF signals to generate filtered RF signals. The one or more channel recovery elements (40 and/or 60) process the filtered RF signals to provide baseband signals corresponding to one or more frequency channels.</p> |
