MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202611050324 A) filed by Indian Institute Of Technology, Rupnagar, Punjab, on April 20, for 'system and method for multi-stage blind wideband spectrum sensing and signal parameter estimation.'
Inventor(s) include Satyam Agarwal; and Arhum Ahmad.
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: "A system and method for blind wideband signal detection and signal parameter estimation. A wideband signal received by wideband RF front-end module (100) and pre-processed to generate spectral representation, derives noise-only spectral region based on hardware-aware spectral characteristics. A noise avoidance coefficient is derived by noise estimation unit (132) from noise-only spectral region via ordered-statistic process. Candidate signal activity is identified by decision unit (138) using dual-condition evaluation of peak density, inter-peak slope characteristics. Refinement is performed on identified candidate spectral regions through bandwidth narrowing and higher-resolution spectral analysis. The noise reference is scaled across refinement stages without recomputing ordered-statistic estimation. Confirmed signals are processed by post processing module (160) determine parameters including center frequency and bandwidth. The system enables reliable detection of unknown signals in wideband and noise-dominated environments without prior knowledge of signal characteristics."
