Abstract
Official abstract text for this publication.
Systems and methods in accordance with embodiments of the invention include converting satellite signals to an intermediate frequency signal for content decoding, and selecting modulated digital data within the satellite signals for content decoding using digital signal processing. One embodiment includes a system configured to select at least one content channel from an input signal including a plurality of content channels modulated onto a carrier, the system including: a digital channelizer switch including: a high speed analog to digital converter configured to digitize an intermediate frequency signal; a digital channelizer configured to digitally tune a content channel from the digitized intermediate frequency signal; and a high speed digital to analog converter configured to generate an analog output signal using the content channel digitally tuned from the digitized intermediate frequency signal by the digital channelizer.
First claim
Opening claim text (preview).
What is claimed is: 1. A system for selecting content channels modulated onto a carrier, the system comprising: a mixer configured to convert the content channels to an intermediate frequency signal; a high-speed analog-to-digital converter configured to digitize the intermediate frequency signal; a digital channelizer configured to digitally select content channels from the digitized intermediate frequency signal, where the digital channelizer comprises: at least one poly-ph…
