Title: Innovations of Vladimir Pavlovic in Linear Transmission Technology

Introduction

Vladimir Pavlovic is an accomplished inventor based in Vancouver, Canada. He has made significant contributions to the field of linear transmission technology, holding 2 patents that showcase his innovative approach to signal processing.

Latest Patents

His latest patents include a "Method and apparatus for linear transmission by direct inverse modeling" and a "Linear transmitter using predistortion." The first patent describes a system for linearly transmitting an amplified output signal using predistortion. This method employs a straight inverse modeling scheme to accurately determine the inverse of the distortion caused by a power amplifier in an RF transmitter. By modeling 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 complex coefficients stored in a lookup table (LUT) to implement a digital filter that compensates for modulation envelope memory effects.

The second patent outlines a linear transmitter that incorporates a modulator, predistorter, digital quadrature modulator, upconverter, power amplifier, and antenna. This transmitter features a feedback loop that includes a coupler, downconverter, digital quadrature demodulator, and trainer. The digital data is modulated and predistorted before amplification, ensuring that the output signals are closely aligned with the original input signals.
