Latest Patents

One of her latest patents is titled "Envelope limiting for polar modulators." This invention provides a system that intelligently compresses the amplitude modulation in a polar modulator, allowing it to be implemented with a single-stage variable gain amplifier. By limiting the amplitude modulation range on the low side, it prevents the collapse of the transmit signal's time-varying envelope and eases circuit implementation. Additionally, limiting the amplitude modulation range on the high side reduces the peak-to-average ratio of the waveform, thereby improving the efficiency of the radio transmitter.
