Latest Patents

Yan Guo holds a patent for a "Method and apparatus for linear transmission by direct inverse modeling." This invention presents a system for linearly transmitting an amplified output signal using predistortion. The 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 invention avoids the computationally intensive inversion required by conventional methods. The predistorter system utilizes complex coefficients stored in a lookup table (LUT) to implement a digital filter that compensates for distortion effectively.
