Abstract: Embodiments of the present invention provide a method and an apparatus for demodulating a physical random access channel signal. The method includes: acquiring a down-sampling sequence of a PRACH demodulation signal, and acquiring a power sequence of the down-sampling sequence; determining a position of a sounding reference signal sampling point in the down-sampling sequence according to the power sequence; and eliminating the sounding reference signal sampling point in the down-sampling sequence according to the position of the sounding reference signal sampling point, so as to perform PRACH coherent detection on a down-sampling sequence obtained after the sounding reference signal sampling point is eliminated. In the method and the apparatus for demodulating a physical random access channel signal in the embodiments of the present invention, interference from a sounding reference signal can be restrained and false alarms in PRACH detection can be reduced.

Abstract: A pressure detection structure and an electronic device are provided that improve sensitivity and accuracy of pressure detection. The pressure detection structure includes: N piezo-resistors connected at the first dielectric layer to form a Wheatstone bridge, where an opening of a first cavity is provided on the first surface of the substrate. The two ends, in a first direction, of the vertical projection of a first piezo-resistor among the N piezo-resistors on a contact surface between the N piezo-resistors and the first dielectric layer are located respectively on the two sides, in the first direction, of the vertical projection of the first cavity on the contact surface. The long side of a second piezo-resistor among the N piezo-resistors is perpendicular to the first direction, and the vertical projection of the second piezo-resistor on the contact surface does not overlap with the vertical projection of the first cavity.
