Latest Patents

One of Weinstein's latest patents is titled "Phase-jitter compensation using periodic harmonically related components." This invention involves a quadrature amplitude-modulated (QAM) data signal receiver that employs a phase compensation arrangement before the equalizer. The arrangement is designed to utilize the assumption that the frequency components typically present in phase perturbance are power-line related. This enables the phase compensator to maintain relatively low complexity compared to the equalizer. The compensator is 'pretuned,' allowing for adaptive adjustments of the phase and amplitude of the frequency components, resulting in a stable arrangement with a suitable convergence rate.

Another significant patent is "Timing acquisition in voiceband data sets." This invention describes a multipoint data communication system where a master modem and multiple tributary modems are interconnected via respective transmission channels. The adaptive equalizer circuitry in the master modem equalizes the channel from a particular tributary by multiplying samples of signals received from that tributary by an ensemble of tap coefficients. The timing-acquisition circuitry within the master modem adjusts the phase of the sampling circuitry at the start of transmission, ensuring that received signals are sampled at the correct time points.
