Title: Qun Shi: Innovator in Communication Technology
Introduction
Qun Shi is a notable inventor based in Plainsboro, NJ (US), recognized for his contributions to communication technology. He holds a total of 3 patents, showcasing his innovative approach to enhancing communication systems.
Latest Patents
One of his latest patents is titled "Method and apparatus for radio synchronization detection in a rake receiver." This invention enhances reception in communication systems by performing radio synchronization detection after multipath signal components are combined via a Rake combiner. In this system, plural multipath signal components transmitted by a transmitter are received and correlated with a known spreading code. The correlated multipath signals are analyzed to identify correlation peaks, and those that exceed a multipath threshold are selected and combined to produce a coherent signal. A synchronization event is declared when this combined signal surpasses an adjusted synchronization threshold, allowing for successful decoding.
Another significant patent is the "System and method for direction finding and geolocation of emitters based on line-of-bearing intersections." This technique determines the geolocation of a radio frequency (RF) emitter using pair-wise line-of-bearing intersections derived from signal-to-noise ratios of transmitted signals received at a sensor. It can be employed with ground-based vehicles or small unmanned air vehicles (UAV), providing reliable geolocation estimates of RF emitters of interest.
