Abstract

An apparatus and method to transmit and receive messages within and near the noise floor by pulsed signals that are time synchronized and are not easily intercepted by use of frequency and time slots as well as intermittent transmissions.

First claim

I claim:

1. An apparatus for enhancing communication Signal to Noise Ratio, the apparatus comprising,
a transmitter;
a clock source connected to said transmitter;
a timer connected to said clock source, wherein said timer is set by said clock source;
a processor connected to said transmitter, said processor receiving a clock signal from said clock source to set a transmission frequency, said transmitter transmitting a signal at said transmission frequency;
a receiver configured with another clock source, said receiver being substantially time-of-day synchronized with said transmitter;
said receiver uses said another clock source to substantially match a frequency of a transmitted signal;
wherein said receiver performs a time enhanced coherent integration on the signal transmitted by said transmitter to enhance signal to noise ratio in said transmitted signal and to extract a message contained within said signal.

2. The apparatus of claim 1 wherein the receiver also performs a non-coherent integration to extract a message contained within said transmitted signal.

3. The apparatus of claim 1 wherein said transmitter transmits pulsed signal having frequency slots.

4. The apparatus of claim 1 wherein said transmitter transmits pulsed signal having frequency slots, each frequency slot encodes a value and the receiver receives the each frequency slot to decode the value.

5. The apparatus of claim 1 wherein said transmitter transmits a value encoded in at least one or more of frequency slot, time slot, and phase shift.

6. The apparatus of claim 1 wherein said transmitter transmits in a time slot, said time slot is determined by power of the signal and a duration of a transmission and said receiver matches the duration of said transmission.

7. The apparatus of claim 1 wherein said transmitter transmits in a time slot, said time slot is determined by power of the signal and a duration of a transmission and said receiver matches the duration of said transmission, said transmission encoding a value and said receiver decoding said value.

8. The apparatus of claim 1 wherein said transmitter transmits encoded value(s) in at least one or more of frequency slot, time slot, phase shift, and said receiver using a heuristic to decode said encoded value(s).

9. The apparatus of claim 1 wherein said clock source is an AM broadcast station signal.

10. The apparatus of claim 1 wherein said signal is varied by phase to create interference and reinforcement in predetermined zones.

11. The apparatus of claim 1 wherein said signal is varied by phase to create interference and reinforcement in predetermined zones.

12. The apparatus of claim 1 wherein said signal is varied by phase to create moving zones of interference and reinforcement at predetermined locations and at predetermined speeds and directions.

13. The apparatus of claim 1 wherein matching of said transmitter and said receiver to clock sources is better than 1/(frequency*1.5).

14. A signal to noise ratio (SNR) enhancement apparatus, the apparatus comprising:
a receiver coupled to an antenna, the receiver comprising:
a clock source, wherein the receiver configured to substantially time synchronize with a transmitter, and wherein the receiver further configured to substantially match a frequency of a signal transmitted from the transmitter and received through the antenna, and
a coherent integration unit configured to perform a time enhanced coherent integration on the signal to enhance SNR in the signal by integrating samples of a continuous waveform series of each bit within the signal and integrating samples and to extract a message contained within the signal.

15. The signal to noise ratio (SNR) enhancement apparatus of claim 14 , wherein the receiver further comprises a non-coherent integration unit configured to perform a non-coherent integration to extract the message.

16. The signal to noise ratio (SNR) enhancement apparatus of claim 14 , wherein the coherent integration unit is integrated into a field programmable gate array (FPGA).

17. The signal to noise ratio (SNR) enhancement apparatus of claim 14 , wherein the receive further comprises the antenna.
