Latest Patents
One of his notable inventions is the "Random Walk Filter Timing Recovery Loop." This timing recovery loop incorporates a random walk filter counter that counts early, nominal, and late arrivals of data transition pulses from an input baseband signal. It provides magnitude counts that are compared to a threshold value. When this threshold is exceeded, it results in a delay adjustment of the generated timing pulses, ensuring synchronization with the actual bit timing for maintaining bit timing lock. This innovation is crucial for reliable data detection and reconstruction of digital bit streams, especially in changing channel environments.
Another significant patent is the "High Power Amplifier Predistorter System." This adaptive predistorter system receives and predistorts an input signal to linearize the output signal of a nonlinear high power amplifier. It utilizes closed-loop feedback of the output signal in complex form at baseband to adaptively change the predistortion amount in response to the changing characteristics of the high power amplifier.
