MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202531129236 A) filed by National Institute Of Technology, Rourkela, Orissa, on Dec. 19, 2025, for 'system and method for fpga-based group-theoretic dft and idft with modular dsp pipeline.'
Inventor(s) include Gupta, Dr. Supratim; and Mr. Abhishek.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a Field-Programmable Gate Array (FPGA)-based system (100) and method (200) for performing digital signal processing over non-abelian finite groups. The system (100) comprises a memory storing precomputed irreducible-representation data in fixed-point format, an input interface (1) for analog-to-digital acquisition, a spectral processing unit (2) configured to execute group-theoretic DFT and IDFT operations, an output interface (3) for digital-to-analog reconstruction, and a control unit (4) for coordinating data flow. A modular, hardware-agnostic architecture separates the data path from the control path, enabling plug-and-play insertion of DSP blocks without modifying master control logic. The method (200) includes acquiring signals through input interface (1), performing spectral transforms using precomputed matrices, optionally inserting DSP modules, and reconstructing analog output via output interface (3). The present invention is applicable to real-time spectral analysis, pattern recognition, secure sensing, industrial monitoring, and embedded signal-processing systems."
