Title: Joseph P McGeehan: Innovator in Signal Processing Technology

Introduction

Joseph P McGeehan is a notable inventor based in Corsham, GB. He has made significant contributions to the field of signal processing, holding a total of 11 patents. His work primarily focuses on advancements in radio transmission and reception technologies.

Latest Patents

Among his latest innovations is the Cartesian loop transmitter. This device is designed for transmitting baseband signals and features a forward path that includes an upconverter, an attenuator with selectable attenuation, and multiple power amplifier stages. The feedback path incorporates a pin diode attenuator and a downconverter, which together provide an error signal indicative of the non-linearity of the forward path. Another significant patent is the full-duplex radio transmitter/receiver. This transceiver achieves cancellation of transmission signals in the receive path by sampling the transmission signals and adjusting their gain and phase before subtracting them from the received signals. This innovative approach minimizes the interference of transmission signals in the received signals, with processing conducted in a digital signal processor at or near baseband.
