Abstract
The disclosed embodiments relate to an apparatus and method for performing frequency translation. The apparatus includes a receiver for receiving and digitizing a plurality of first signals, each signal containing channels and for simultaneously recovering a set of selected channels from the plurality of first signals. The apparatus also includes a transmitter for combining the set of selected channels to produce a second signal. The method of the present invention includes receiving a first signal containing a plurality of different channels, selecting a set of selected channels from the plurality of different channels, combining the set of selected channels to form a second signal and transmitting the second signal
Claims22
An apparatus comprising:
- a receiver for receiving and digitizing a plurality of first signals, each signal containing one or more different channels and for simultaneously recovering a plurality of selected channels from said plurality of first signals;
- and
- a transmitter for combining said plurality of selected channels and producing a second signal.
A method for providing frequency translation comprising:
- receiving a first signal having a plurality of different frequency channels;
- selecting a set of frequency channels from said plurality of different frequency channels;
- combining said set of frequency channels to form a second signal;
- and
- transmitting said second signal.
An integrated circuit for use in a receiving system, which receives signals representing a plurality of channels, the integrated circuit comprising:
- a demultiplexing element for demultiplexing a received sampled signal to produce a plurality of first data streams;
- a transform element for transforming said plurality of first data streams into a plurality of transform output signals, and for transforming at least two of said plurality of transform output signals into a plurality of second data streams;
- and
- a multiplexing element for mulitplexing said plurality of second data streams and outputting a sampled signal.
An apparatus for frequency translation comprising:
- means for receiving a first signal having a plurality of different frequency channels;
- means for translating said first signal into a set of signals representing said plurality of different frequency channels;
- means for selecting (530a-c) a set of channels from said set of signals;
- means for combining said set of channels to form a second signal;
- and
- means for transmitting said second signal.
