Title: The Innovations of Wen Yen Chan
Introduction
Wen Yen Chan is a distinguished inventor based in Thornhill, California, with a total of four patents to his name. His work primarily centers around the optimization of transmitter power efficiency, showcasing his commitment to advancing technology in communication systems.
Latest Patents
One of Chan's latest innovations is a method and apparatus for optimizing transmitter power efficiency. This invention utilizes a peak to average power ratio signal generated from a first mapping function. It selects the appropriate signal corresponding to the data rate or data format of the transmitted signal. The selected signal is then summed with a desired average transmit power signal, leading to a summation signal that is input into a second continuously valued mapping function. This function consists of a table with various power amplifier control signal values, each linked to a peak transmit power. The resulting signals are designed to ensure optimum transmitter power efficiency while accommodating out-of-band spurious emissions and waveform quality requirements. The process further involves mapping the summation signal to a relevant power amplifier control signal value, adjusting parameters such as the bias of the power amplifier.
