Latest Patents

Among his notable inventions is a patent focused on channel diagnostics based on equalizer coefficients. This technology allows a receiver to compensate for skew between input channels by utilizing a calibration method. The receiver estimates the skew by observing coefficients of an adaptive equalizer that adjusts based on the time-varying properties of the multi-channel input signal. Additionally, during real-time operation, channel diagnostics automatically estimate differential group delay and other characteristics by leveraging frequency or polarization averaging approaches. The patent also describes how a DSP reset can be performed upon detecting significant signal degradation, enhancing the reliability of communication.

Another key patent involves a timing recovery system for optical coherent receivers that tackles polarization mode dispersion. This system generates a sampling clock to synchronize the receiver's sampling with the symbol rate of incoming signals received over an optical communication channel. By computing a rotation control signal that represents the accumulated phase shift relative to the sampling clock, the technology ensures precise timing adjustments, thus improving signal clarity.
