MUMBAI, India, Aug. 10 -- Intellectual Property India has published a patent application (202641089948 A) filed by Vellore Institute Of Technology on July 23, 2026, for “a Turbulence-Aware Communication System For Mitigating Self-Interference And Detecting An Energy-Significant Oam Mode Subspace In A Turbulent Rf Channel”.

Inventors include Dr. Abhijit Bhowmick; Dr. Sudhanshu Arya; Dr. Saranya K C; and Dr. Yogesh Kumar Choukiker.

The application for the patent was published on July 31, 2026, under issue no. 31/2026.

Abstract: The present invention relates to a turbulence-aware orbital angular momentum (OAM) communication system and method for mitigating self-interference in a turbulent RF channel. The system includes a transmitter for generating composite OAM signals, a reconfigurable intelligent surface (RIS) with controllable reflecting elements, and an RIS controller that adjusts phase shifts based on channel state information (CSI) feedback. Due to atmospheric turbulence causing mode leakage and conversion, receivers project the received signal onto a broader OAM basis to identify an energy-significant finite mode subspace and decode the intended OAM mode using turbulence-aware equalization. The invention enhances coherent signal combining, suppresses inter-mode interference, reduces decoding complexity, and improves communication performance in multi-user environments. Fig 1 to 9.
