Coordinated numerical control of sideband energy and modulation compression method for the radio frequency transmission of high speed data
View Patent ↗An RF signal compression technique used to transport high bit-rate data over wired or wireless means using modulated radio frequency carrier waves whose purpose is to reduce the number of radio carrier modulation events, thus reducing the amount of radio sideband emissions, while increasing the amount of information conveyed by coordinating the modulation events. More specifically an improved compression method with coordinated padding for various methods of modulation by which the spectral channel width occupied by the radio signal and the power spectrum density of said signal can be controlled by numerically adjusting the coding format in a coordinated manner allowing for coordinated modulation events which permits multiple transmissions in a coverage area greatly increasing the amount of information transmitted and available users.
1. A method of generating coordinated modulation signals using compressed integer cycle or impulse modulation on a carrier to avoid collocated signal interference comprising the steps of:
grouping wavelets of the carrier into wavelet groups containing two or more wavelets;
receiving an information stream as a binary data sequence of first and second binary states;
grouping said binary data sequence of first and second binary states into binary groups of two or more first and second binary states;
correlating one of each said wavelets in said wavelet groups with one of each possible binary values of each said binary groups;
modulating said carrier in accordance with said binary data sequence by altering the amplitude, frequency, or phase of one of each said wavelets in said wavelet groups corresponding to one of each said binary values of said binary groups forming altered wavelet groups; and,
inserting one or more unaltered wavelet groups at the beginning or at the end of each of said altered wavelet groups resulting in a coordinated compressed binary modulated carrier.
2. The method of claim 1 wherein:
the modulating of said carrier is carried out by altering the amplitude, frequency, or phase of said wavelets while minimizing sideband distortions of said carrier.
3. The method of claim 1 comprising the additional step of:
reducing of harmonics produced from modulating said carrier by filtering said sideband limited compressed binary modulated carrier.
4. The method of claim 1 comprising the additional step of:
broadcasting said coordinated compressed binary modulated carrier.
5. A method for demodulating coordinated compressed binary information that was derived from a binary information stream composed of a binary data sequence of first and second binary states that was integer cycle or impulse modulated onto a carrier in which the carrier has been modulated in accordance with said binary data sequence by grouping said wavelets into wavelet groups containing two or more wavelets; receiving said information stream as a binary data sequence of first and second binary states; grouping said binary data sequence of first and second binary states into binary groups of two or more first and second binary states; correlating one of each said wavelets in said wavelet group with one of each possible binary values of each said binary groups; modulating said carrier in accordance with said binary data sequence by altering the amplitude, frequency, or phase of the one of each said wavelets in said wavelet groups corresponding to one of each said binary values of said binary groups forming altered wavelet groups; and inserting one or more unaltered wavelet groups at the beginning or at the end of each of said altered wavelet groups resulting in a coordinated compressed binary modulated carrier which was broadcasted to avoid collocated signal interference comprising the steps of:
receiving said broadcasted coordinated compressed binary modulated carrier;
demodulating and decompressing said coordinated compressed binary modulated carrier by ignoring said one or more unaltered wavelet groups at the beginning or at the end of each of said altered wavelet groups and detecting the respective amplitude, frequency, or phase of said wavelets to identify said altered wavelets in said altered wavelet groups and correlating to said binary values of said binary groups; and,
reconstructing said binary data sequence from said binary values of said binary groups resulting in regeneration of said information stream.
6. A modulation and demodulation method for modulation systems using compressed integer cycle or impulse modulation on a carrier to avoid collocated signal interference comprising the steps of:

correlating one of each said wavelets in said wavelet groups with one of each possible binary values of each said binary groups;
modulating said carrier in accordance with said binary data sequence by altering the amplitude, frequency, or phase of one of each said wavelets in said wavelet groups corresponding to one of each said binary values of said binary groups forming altered wavelet groups;

demodulating and decompressing said coordinated compressed binary modulated carrier by ignoring said one or more unaltered wavelet groups at the beginning or at the end of each of said altered wavelet groups and detecting the respective amplitude, frequency, or phase of said wavelets to identify said altered wavelets in said altered wavelet groups and correlating to said binary values of said binary groups; and,
reconstructing said binary data sequence from said binary values of said binary groups resulting in regeneration of said information stream.
7. The method of claim 6 wherein:
the modulating of carrier is carried out by altering the amplitude, frequency or phase of said wavelets while minimizing sideband distortions of said carrier.
8. The method of claim 6 comprising the additional step of:
reducing of harmonics produced by modulating said carrier by filtering said carrier.
