Abstract

The invention discloses a bluetooth signal processing method and device. Wherein, the method includes: receiving the bluetooth signal to be processed, and filtering the bluetooth signal to obtain the first target signal; obtaining the power value of the first target signal, performing first alpha filtering on the power value to obtain the first power, and The power value is processed by the second alpha filter to obtain the second power, wherein the first alpha value corresponding to the first alpha filter is greater than the second alpha value corresponding to the second alpha filter; obtain the power difference between the first power and the second power ; Judging whether the power difference is greater than a preset threshold; if the power difference is greater than the preset threshold, determine that the Bluetooth signal contains the second target signal. The invention solves the technical problem of inaccurate detection of the arrival time of the useful signal in the bluetooth signal in the prior art.

Description

technical field [0001] The invention relates to the technical field of digital information transmission, in particular to a method and device for processing Bluetooth signals. Background technique [0002] Bluetooth (Bluetooth) is one of the short-range wireless communication standards. Compared with wireless communication technologies such as infrared and wireless 2.4G, Bluetooth transmission is more stable and can be applied to short-distance data transmission, for example, short-distance audio transmission. Bluetooth signal transmission technology can be divided into basic rate (BR, Base Rate) Bluetooth technology, extended rate (EDR, Enhanced DataRate) Bluetooth technology and Bluetooth Low Energy (BLE, Bluetooth Low Energy) technology. The Bluetooth signal is mainly composed of a preamble sequence, an access code field, and a payload segment. According to different Bluetooth standards, its length is also different. Table 1 provides a signal structure of a 1Mbps low-pow...
