Latest Patents

Afashi's latest patents include a method and system for compensating for estimated distortion in a transmitter by utilizing a digital predistortion scheme with a single feedback mixer. This invention presents aspects of a system that may include at least one circuit enabling the generation of an output signal in response to one or more generated input signals. A feedback signal is generated within a single feedback mixer circuit that performs a frequency mix-down operation on the generated output signal. The generated feedback signal is inserted at one or more insertion points in a receiver, enhancing the overall performance of the system.

Another notable patent is a method and system for enhancing efficiency by modulating power amplifier gain. This invention comprises a power amplifier gain modulator that modifies the amplitude of a digital baseband signal. A baseband processor computes a first gain value based on this modification and subsequently computes a second gain value based on the first. The power amplifier then generates an RF output signal based on the modified digital baseband signal and the second gain value.
