Abstract

The embodiment of the present invention discloses a method, device, device and computer storage medium for obtaining the first path of arrival position in a UWB system. The method may include: according to all pilot symbols in the first subfield in the pilot field of the received signal Obtain the reference position of the sampling window from the correlation value of the element at the corresponding position; determine the sampling window according to the reference position of the sampling window and the window length of the sampling window; Correlation values ​​and thresholds of elements in corresponding positions of all pilot symbols in the sampling window to obtain the first path position.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of wireless communication, and in particular to a method, device, device and computer storage medium for obtaining a first-arrival position in a UWB system. Background technique [0002] At present, Impulse Radio Ultra Wide-Band (UWB, Impulse Radio Ultra Wide-Band) technology defined in the 802.15.4 protocol standard of the Institute of Electrical and Electronics Engineers (IEEE, Institute of Electrical and Electronics Engineers) is widely used in application scenarios such as data transmission and positioning. [0003] UWB is a wireless carrier communication technology. Since the transmitter of the UWB system transmits nanosecond-level non-sinusoidal narrow pulses with a very low duty cycle, in the UWB system, the multipath signal received by the receiver is in the are separable in time. Based on the non-overlapping characteristic of pulsed multipath signals in time, each multipath co...
