Latest Patents

One of Zhang's latest patents is titled "Adaptive Equalizer Performance Monitor." This invention relates to a method of equalizer performance monitoring, which includes receiving a signal at a receiver and adjusting the step size of an adaptive equalizer in response to changes in the state of polarization (SOP) of the received signal. The adaptive equalizer communicates with one or more digital signal processing (DSP) components, which are also in communication with the receiver. The method further involves increasing or decreasing the step size of the adaptive equalizer based on updates to one or more filter coefficients.

Another significant patent is "Clock Recovery in Symbol-Rate DSP." This invention outlines a method of clock recovery that includes sampling one or more signals at a symbol rate to generate a set of samples. The process involves zero-padding one or more samples in the set, filtering the zero-padded signals with a filter to generate a set of filtered samples, and modifying the filtered samples by applying a non-linear operator to produce an output comprising a spectral correlation.
