MUMBAI, India, Feb. 27 -- Intellectual Property India has published a patent application (202621003699 A) filed by Shri G S Institute Of Technology And Science, Indore, Madhya Pradesh, on Jan. 13, for 'orbital angular momentum multiplexing-based high-capacity wireless transmission system.'
Inventor(s) include Gireesh G Soni; Abhishek Tripathi; and Shilpi Gupta.
The application for the patent was published on Feb. 27, under issue no. 09/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to an Orbital Angular Momentum (OAM) multiplexing-based high-capacity wireless transmission system (200) comprising a transmitter and a receiver for simultaneous multi-channel data transmission using electromagnetic waves carrying distinct OAM modes. The transmitter includes a channel mapper (101) configured to assign multiple data streams to different OAM modes, an OAM generation circuit (106) implemented using a Butler matrix or discrete Fourier transform network, a phase shifter network (107) for precise phase control, and a combiner/multiplexer (112) coupled to a uniform circular array or metasurface antenna (109) for radiating spatially orthogonal OAM beams within a single frequency band. The receiver comprises an OAM separation circuit (120), a digital signal processing and mode separation engine (124), an adaptive equalizer and crosstalk mitigator (125), and a forward error correction decoder (127) for reliable data recovery. The system (200) further includes a system control manager (133), an intelligent calibration engine (135), a beam alignment controller (134) with a pilot beacon unit (136), a power management unit (139), and an environmental sensing suite (140) to dynamically compensate for misalignment, phase distortion, and environmental variations. The integrated configuration enables spectrally efficient, high-throughput, and robust wireless communication suitable for next-generation networks."
