Title: Innovations by Rachel E Learned: Patenting Communication Solutions
Introduction
Rachel E Learned, based in Waltham, MA, is an accomplished inventor with a remarkable portfolio of 23 patents that demonstrate her innovative contributions to communication technologies. Her work primarily focuses on mitigating signal interference and enhancing the efficiency of communication systems.
Latest Patents
Among her latest patents, two notable inventions stand out. The first is a method for mitigating communication signal interference using adaptive transmit power. This invention addresses the challenge of ensuring reliable transmission in environments with multiple users by adjusting the transmit power based on the observed packet drop rate. If the packet drop rate exceeds a predetermined maximum, the method suggests a decrease in transmit power, which may also involve lowering the transmitter's coding rate and modulation level.
The second patent is a method and apparatus for determining a receiver beam in a co-existence cognitive radio environment. This innovation includes a sophisticated technique where the starting angle is determined based on the direction of a signal of interest. The method iteratively adjusts the beam away from this angle to calculate different grades, ultimately selecting the best beam for receiving and decoding the signal of interest even amidst multiple interfering signals.
