Latest Patents

Farias holds a patent for a "Method and apparatus for reduction of sinusoidal phase jitter in a high-speed data modem." This invention involves an apparatus designed to cancel sinusoidal varying phase jitter in a data modem, implemented through firmware using microprocessor technology. The process begins with estimating the frequency and phase of the phase jitter in a first stage. Independently, another stage computes an estimate of the amplitude of the phase jitter. These estimates are then combined to create a composite estimate, which is utilized to eliminate the sinusoidal phase jitter in the demodulator. The technology employs a digital phase locked loop (DPLL) to lock onto the phase jitter components. During a training sequence, the capture range of the phase locked loop is dynamically adjusted to accommodate a wide range of jitter frequencies. This innovative approach enhances noise performance while maintaining the ability to lock onto various jitter frequencies.
