Latest Patents

Wendy's latest patents include a spur cancellation system for modems. This innovative modem design features a modulator and a demodulator, where the demodulator incorporates a direct current removing (DCR) circuit. This circuit transitions between an acquisition mode, operating with a first loop gain, and a tracking mode, functioning with a second loop gain that is smaller than the first. The timing of this transition is programmable, enhancing the modem's adaptability. Another notable patent is for frequency estimation, correction, and noise suppression for modems. This invention includes a frequency-shift keying (FSK) demodulator that utilizes a digital phase-locked loop (DPLL) based frequency estimator. This technology converts a phase signal to a frequency signal, tracks the direct current (DC) component of the frequency signal, and improves the symbol-level signal to noise ratio (SNR) through an average filter.
