MUMBAI, India, Oct. 31 -- Intellectual Property India has published a patent application (202514014177 A) filed by Samsung Electronics Co. Ltd., Gyeonggi, Republic of Korea, on Feb. 19, for 'interference cancellation circuit and operating method thereof, and channel impulse response estimation circuit.'
Inventor(s) include Joontae Kim.
The application for the patent was published on Oct. 31, under issue no. 44/2025.
According to the abstract released by the Intellectual Property India: "An interference cancellation circuit includes finite impulse response (FIR) filter configured to set a channel impulse response (CIR) coefficient for each transmission path for a transmission signal and obtain a CIR-adapted transmission signal by applying the CIR coefficient to the transmission signal, a kernel generation circuit configured to generate an interference model based on the CIR-adapted transmission signal, an adaptive filter configured to estimate an interference signal for each reception path by estimating an interference model coefficient for the interference model and generate an interference-cancelled signal by filtering out the interference signal from a reception signal, and a CIR estimation circuit configured to estimate the CIR coefficient in a next sample period based on the interference-cancelled signal through a backpropagation method and transmit the estimated CIR coefficient to the FIR filter."
