Title: Rollin E Langseth: Innovator in Radio Transmission Technologies

Introduction

Rollin E Langseth is a notable inventor based in Colts Neck, NJ (US), recognized for his contributions to radio transmission technologies. He holds a total of five patents that showcase his innovative approaches to combating multipath fading in communication systems.

Latest Patents

One of Langseth's latest patents is titled "Matched filter for combating multipath fading." This invention discloses a carrier and timing recovery technique designed to address the phase effects of multipath fading during radio transmission. The technique utilizes a mathematical model of multipath fading, employing a test variable generator to develop test variables that characterize the multipath distortion. A processor then derives coefficients of weighting measures from these test variables, which adjust a matched filter to enhance the use of portions of the received radio signal with higher signal-to-noise ratios. This technique also compensates for multipath phase perturbations and is compatible with maximum-likelihood sequence detection techniques.

Another significant patent is "Cooperating arrangement for diversity stations." This invention relates to a system of space diversity stations interconnected by a communication link. Each station communicates independently with a remote point while managing traffic related to separate service regions. In the event of a fade condition at one station, it alerts the other station, enabling both to route communications effectively, ensuring continuous service.
