Title: The Innovative Contributions of Andreas Gebhard

Introduction

Andreas Gebhard is a notable inventor based in Linz, Austria. He has made significant contributions to the field of wireless technology, holding a total of 5 patents. His work focuses on enhancing the performance of wireless devices through innovative signal processing techniques.

Latest Patents

One of his latest patents is the "Multiple Modulated Spur Cancellation Apparatus." This apparatus is designed for wireless devices and includes baseband processing circuitry that generates a digitized downconverted signal from a received radio frequency (RF) signal. It features estimation circuitry that detects blocker signals exceeding a predetermined power threshold and maps these signals to harmonic frequencies associated with multiple carrier frequencies. Additionally, the apparatus incorporates reference signal generation circuitry to create a reference signal based on these harmonic frequencies, which is then used by cancellation circuitry to remove distortion from the digitized downconverted signal.

Another significant patent is the "Second Order Intermodulation Cancellation for RF Transceivers." This method involves estimating a transmit leakage signal for a duplexer within a transceiver. The process includes squaring the envelope of the estimated transmit leakage signal, generating a replica signal based on this squared envelope, and subtracting the replica from the total received signal to produce a wanted received baseband signal.
