Ground-Based Multi-Source Interference Pattern-Based Communication System

Abstract

The ground-based multi-source interference pattern-based communication system relies on binary data extraction from the actual physical interference pattern created in space by coherent radio frequency (RF) signals simultaneously transmitted from at least two physically separate ground-based transmitter stations. The system is scalable and can include any number of transmitters and receivers. The system encodes data over a fringe gap calculated using the distance between transmitters, carrier frequency, and receiver location. The receiver unit can be located as a mobile device, fixed station, or vehicle-mounted platform. The system offers full-duplex communication. The system can operate as a parallel channel independent of the existing internet infrastructure or integrated into the existing infrastructure. It can operate at different frequencies and phase values ​​without being tied to a specific frequency range. Security, if desired, relies on phase values ​​determined by a quantum random number generator (QRNG) in each communication session.It provides secure, high-speed, and low-latency communication at the physical layer in local areas without satellite reliance. Multipath effects are reduced with directional antennas and adaptive filtering. The system can be used in areas such as smart cities, industrial facilities, military bases, airports, ports, and emergency communication networks.

It relies on the simultaneous, coherent radio frequency (RF) signal transmission from the station (1, 2). The system is scalable, allowing for any number of transmitter stations and any number of receiver units. It may include. When signals overlap in free space, a principle of classical wave superposition applies. An entry pattern is formed. The total amplitude formed at the receiver point (5) by the signals of the same frequency emitted from two sources (1, 2), It depends on the path difference from the source to the receiver. Constructive interference is equal to integer multiples of the wavelength. It occurs at the points where it is located. The data encoding mechanism is the temporal relationship between successive fringe peaks of the receiver (5). or relies on continuously measuring the spatial range. Constructive interference peaks are binary “1”, destructive The gap points can be evaluated as binary “0” or vice versa. Whichever case is “1” or “0” It is a design choice that will be defined as follows. The system is a parallel data transmission channel that operates independently of the existing internet infrastructure. The same It can also be used by integrating it into the existing internet infrastructure. Fiber optic, copper or satellite. Data is transmitted solely via the RF interference pattern, without the need for connecting cables. The receiver unit (5) can be positioned as a mobile device, fixed station or vehicle-mounted platform. The receiver's location is limited by predefined coordinates; a different location... The listener observes a completely different interference pattern and cannot decipher the data. Positioning system (4) determine the coordinates of the receiver unit (5) and with the predefined position. It allows for comparison. The system offers full duplex communication. The receiver unit (5) also acts as a transmitter, transmitting stations 35 (1, 2) can also function as a receiver. In this way, both data reception and reception can be done through the same hardware. Data transmission is possible. 2 The multipath effect occurs when a signal in a dense urban environment is reflected off the direct path. This occurs as a result of reaching it. The invention uses directional antennas (9) to reduce this effect. Beamform acquisition with spatial suppression of reflected signals and, if desired, adaptive signaling. The pattern measured with the expected fringe pattern from the known transmitter geometry with the filtering module (10). It offers methods for filtering out the discrepancies between them in real time. The system uses frequency division multiplexing (FDM) by simultaneously utilizing multiple frequency channels. It can increase the total data rate. The system can use different frequencies without being tied to a specific frequency range. It can be operated at specific phase values. For multiple transmitter stations to operate simultaneously, real-time phase switching between transmitters is required. Synchronization is performed using GPS time reference or an internal high-precision oscillator. It is provided. If a security layer is desired, a quantum random number generator (QRNG) (8) can be used in each communication session. It can rely on the generated phase values. These values ​​are only available to authorized receivers (5) and transmitters (1, 2) It is known by the phase control unit (3), the transmitters according to the values ​​produced by QRNG (8) Adjusts the phase output.
