Intellectual Property India Publishes Patent Application for 'Low-Complexity Hardware System And A Method For Empirical Mode Decomposition Of Signals' Filed by Indian Institute Of Technology

MUMBAI, India, Feb. 13 -- Intellectual Property India has published a patent application (202641008868 A) filed by Indian Institute Of Technology, Hyderabad, Telangana, on Jan. 29, for 'low-complexity hardware system and a method for empirical mode decomposition of signals.'

Inventor(s) include Cheduluri Ganesh; and Amit Acharyya.

The application for the patent was published on Feb. 13, under issue no. 07/2026.

According to the abstract released by the Intellectual Property India: "The present disclosure relates to a low-complexity hardware system for empirical mode decomposition (EMD) of non-linear and non-stationary signals. The system receives an input signal. A sifting module (106) includes an extrema identification (EI) module (108) for detecting maxima and minima with corresponding values and locations, from the input signal. The sifting module (106) further comprises a cubic spline interpolation (CSI) module (110) including a CORDIC-based tri-diagonal matrix algorithm (TDMA) unit (112), a spline coefficient computation (SCC) unit (114), and a spline formulation (SF) unit (116) for generating upper and lower envelopes. A mean computation module (118) computes a mean signal, which is subtracted from the input signal using a first subtractor module (120) to generate an IMF candidate signal. An IMF extractor module (122) extracts an IMF upon satisfying predefined IMF conditions, and a second subtractor module (124) generates a residual signal."
