Latest Patents
Hua Wang's latest patents include innovative methods and apparatus for reducing the average-to-minimum power ratio in communications signals. This invention features a baseband circuit for a communications transmitter that includes a baseband modulator, a pulse-shaping filter, and an AMPR reduction circuit. The baseband modulator generates a sequence of symbols formatted in accordance with a non-constant envelope modulation scheme. The pulse-shaping filter band-limits the sequence of samples to provide a refined output. The AMPR reduction circuit analyzes and modifies samples in the sequence, ensuring optimal performance.
Another significant patent is the high-efficiency all-digital transmitter. This invention utilizes all-digital power amplifiers and various mapping techniques to generate an output signal that closely reproduces a baseband signal at a carrier frequency. The system includes a baseband signal generator that quantizes the signal using a signal processor and a quantization map. The DPA control mapper outputs control signals to phase selectors, which then produce waveforms at the carrier frequency. Each DPA in the array outputs a power signal based on its assigned weight and the phase of the received waveform, resulting in a combined power signal that effectively reproduces the baseband signal.
