Latest Patents

One of Zhao's latest patents is titled "Method and equipment for regulating dynamically an average area of a channel estimation." This invention relates to a method and apparatus for adjusting the average interval of channel estimation dynamically based on Doppler-shift. The method involves estimating Doppler-shift using level cross rate (LCR) according to the varying speeds of mobile terminals. It determines the optimal average interval of channel estimation based on the relationship between the existing Doppler-shift and the optimal average interval. This dynamic adjustment allows coherent receivers to achieve optimal estimation performance at different moving speeds. The apparatus includes several modules, such as a channel estimation module and a Gaussian noise power estimation module.

Another significant patent is the "Pilot channel tracking method based on multipath barycenter tracking loop." This invention discloses a method for pilot channel tracking that evaluates multipath fading channel parameters and calculates the barycenter of a multipath energy window. The method improves tracking performance and timing recovery stability of spread spectrum receivers by eliminating the need to individually track each delay path. This innovation reduces hardware requirements and enhances the efficiency of coherent spread spectrum receivers.
