Abstract

A system for the transmission and reception of wide-band real time multi-channel signals for video, audio, facsimile and/or data information, over a single or multiple satellite transponder, or over a carrier of available bandwidth for program distribution using single sideband suppressed carrier amplitude modulation which requires, for example, only 6 MHz of radio frequency bandwidth to transmit a full NTSC color television channel and which permits the use of small apertured dishes and simple conversion for the consumer'"'"'s television receiver, for a nationwide signal distribution or, wherever television reception is wanted, at an economical cost.

Claims

1. A communication system for use in conjunction with a transponder means of a particular capacity and having separate information channels including:

modulation and frequency allocator input circuit means for receiving a plurality of separate program signals representing different information channels having a particular total bandwidth, and which includes modulator means, and combiner means coupled to said modulator means for combining said program signals into a coherent gate vesta energy output signal; and

energy processor means coupled to said input circuit means and responsive to said coherent gate vesta energy output signal for producing a wide-band multiple channel signal corresponding to the capacity of the transponder means for distributing said separate program signals via satellite uplink to subscriber receivers.

2. The communication system defined in claim 1, in which said input circuit means includes circuitry for producing a coherent gate vesta energy output signal which comprises a set of wide spectrum phase locked sequentially assigned frequency coherent signals.

3. The communication system defined in claim 2, in which said coherent gate vesta energy processor means responds to said coherent gate vesta energy signal from said input circuit means for enhancing desired coherent energy components thereof and for suppressing undesired non-coherent components thereof.

4. The communication system defined in claim 2, in which said coherent gate vesta energy processor means comprises:

a pair of double-balanced modulators;

in-phase splitter circuit means coupled to said modulators and responsive to said coherent gate vesta energy signal from said input circuit means for splitting said signal into two equal and coherent gate vesta energy sources.

5. The communication system defined in claim 4, in which said double-balanced modulators serve respectively to up-convert and down-convert the frequency of said coherent gate vesta energy signal.

6. The communication system defined in claim 4, in which said coherent gate vesta energy processor means includes combiner filter means coupled to said double-balanced modulators for processing the signal therefrom so as to produce desired coherent energy components of said signal at a first output port and undesired non-coherent energy components thereof at a second output port.

7. The communication system defined in claim 6, in which said coherent gate vesta energy processor means includes further means coupled to the output ports of said combiner filter means to enhance the desired coherent energy components and to attenuate the undesired non-coherent energy components.

8. The communication system defined in claim 7, in which said further means comprises a delta/sum magnetic resonant circulator.

9. The communication system defined in claim 2, in which said coherent gate vesta energy processor means includes:

a pair of double-balanced modulators;

in-phase splitter circuit means coupled to said modulators and responsive to said coherent gate vesta energy signal from said input circuit means for splitting said signal into two equal coherent gate vesta energy sources, and to cause said double-balanced modulators respectively to up-convert and down-convert the frequencies of said coherent gate vesta energy signal;

combiner filter means coupled to said double-balanced modulators for processing the signal therefrom so as to produce desired coherent energy components of said signal at a first output port and undesired non-coherent energy components of said signal at a second output port; and

further means coupled to said output ports of said combiner filter means to enhance said desired coherent energy signal components and to attenuate said undesired non-coherent energy signal components.

10. The communication system defined in claim 9, in which said further means comprises a delta/sum magnetic resonant circulator.

11. The communication system defined in claim 1, and which includes a subscriber conversion receiver including:

a bandpass filter tuned to a selected operating receive frequency and having a bandwidth equal to the total bandwidth of the information channels transmitted by the signal; and

heterodyne circuit means coupled to said bandpass filter means and responsive to the output therefrom to provide a band of frequencies acceptable to the input of a selected present-day information receiver.
