A signal angle and signal frequency estimation method, apparatus, device and storage medium are provided. The signal angle and signal frequency estimation method comprises the steps: collecting initial data of a satellite signal by means of an antenna array element; substituting initial data into a signal function, and finding a solution to obtain the satellite signal; and obtaining the angel and frequency of the satellite signal according to the satellite signal. According to the method, in consideration of the non-Gaussian noise environment as well as spatial domain sparse feature and frequency domain sparse feature of the satellite signal, the angle and the frequency of the satellite signal are estimated jointly, thereby facilitating subsequent obtaining and tracking the satellite signal by a satellite navigation receiver.

Pixel driving circuit, driving method thereof, and display panel applied thereof

The invention relates to a pixel unit of a dynamic vision sensor. The pixel unit comprises a pixel photosensitive circuit for detecting an optical signal, and generating and outputting an electrical signal when a change in the optical signal is detected; and a communication circuit connected to the pixel photosensitive circuit; and further comprises: a neighborhood denoising circuit connected to the pixel photosensitive circuit, the communication circuit and other pixel units in four neighborhoods, for controlling&#x2014;whether the communication circuit outputs the electrical signal. In embodiments of the invention, when a pixel unit executes a response trigger event for an optical signal, and if at least three of the pixel units in the four neighborhoods are in a non-response state, the pixel unit does not respond, thereby effectively avoiding the generation of isolated noise, and having beneficial effects of a fast processing speed and a high denoising accuracy.
