With a total of 7 patents to his name, his work has had a lasting impact on various applications in the industry.

Latest Patents

One of his latest patents is titled "Phaselock Threshold Correction." This invention involves a noise estimator for threshold correction of a receiver. The system includes a low pass filter designed to remove wideband noise from an input signal that contains both a signal component and a noise component. The output of the wideband filter is directed to a square-law power detector, which then feeds into an envelope detector. The envelope detector provides the instantaneous envelope of the input signal, which is further processed through a low pass filter for time averaging. This output is also sent to a differential network, generating a signal that represents the difference between the instantaneous envelope and the time-averaged statistical envelope. This difference signal is then processed to estimate the noise component of the input signal.
