Latest Patents
Gal's latest patents include innovative methods for digital pre-distortion. One of his notable inventions is a fixed-point conjugate gradient digital pre-distortion (DPD) adaptation method. This method utilizes a DPD actuator to apply a memory polynomial formed with first DPD coefficients to a first input signal, generating a pre-distorted input signal for non-linear electronic devices. The memory polynomial is adaptively modified using a digital predistortion adapter that computes second DPD coefficients through an iterative fixed-point conjugate gradient method. This process enhances the accuracy of the output signal by continuously updating the DPD coefficients.
Another significant patent involves adaptive high-order nonlinear function approximation using time-domain Volterra series. This method compensates for non-linearities in input signals, ensuring high performance in digital pre-distortion. It includes a digital predistortion block with multiple IQ predistorter cells that utilize lookup tables to generate output signals. The system is designed to adaptively modify the input signal, effectively compensating for distortion effects in non-linear elements.
