MUMBAI, India, Aug. 17 -- Intellectual Property India has published a patent application (202647096297 A) filed by Qualcomm Incorporated on August 10, 2026, for Frequency Domain Phase Constraint.
Inventors include Demirkan, Ismail; Jin, Xiao; and Zhang, James.
The application for the patent was published on August 14, 2026, under issue no. 33/2026.
Abstract: Aspects relate to mechanisms for implementing a frequency domain phase constraint at a decision feedback equalizer (DFE) of a wireless device. The DFE includes a feedforward filter (FFE) operating in a frequency domain. The FFE further includes an accumulator having a main-tap constraint configured to maintain a constant value of a main-tap of the DFE and a phase constraint module configured to maintain a constant phase of a frequency bin associated with the main-tap to produce a timing error used for timing recovery of a receiver of the wireless device.
