Introduction

Armando Cova Garrido is a notable inventor based in Vancouver, Canada. He has made significant contributions to the field of radio frequency (RF) transmission technology. With a total of 2 patents, his work focuses on enhancing the performance and efficiency of RF transmitters.

Latest Patents

Armando's latest patents include the "Model-based adaptive feedforward amplifier linearizer" and the "Method and apparatus for linear transmission by direct inverse modeling." The first patent describes a linear RF transmitter that utilizes an adaptive forward model of the power amplifier in a feedforward linearization system. This innovative approach allows for the calculation of an error signal that represents distortion caused by the power amplifier. The forward model can also account for memory effects, improving the accuracy of the error signal generation.

The second patent outlines a system for linearly transmitting an amplified output signal using predistortion. This method employs a straightforward inverse modeling scheme to determine the inverse of the distortion caused by the power amplifier. By treating the power amplifier as a signal processing block with reversed input and output ports, the need for computationally intensive inversion is eliminated. The predistorter system utilizes a lookup table (LUT) to store complex coefficients, which are then applied to a digital filter for effective predistortion.
