Embodiment 1

[0025] Such as figure 1 As shown, the present embodiment proposes a Bluetooth multi-channel receiving method, the method comprising:

[0026] S101. Receive cyclic redundancy check information and payload data in multiple bluetooth receiving branches.

[0027] Specifically, in the Bluetooth multi-channel receiving method of this embodiment, multiple Bluetooth receiving branches are used to receive wireless signals, wherein the multiple Bluetooth receiving branches are independent of each other and do not interfere with each other. More specifically, each bluetooth receiving branch in this embodiment has the same structure, including a receiving antenna, a radio frequency receiver, and a baseband processor. The receiving antenna receives wireless signals and sends them to the radio frequency receiver for conversion of baseband signals, and baseband processing The device analyzes the baseband signal to obtain cyclic redundancy check information and load data. The subsequent ret...

Embodiment 2

[0062] Such as image 3 As shown, this embodiment proposes a Bluetooth multi-channel receiving system, the system includes a multi-channel Bluetooth receiving branch and a retransmission processor, and the Bluetooth receiving branch includes a receiving antenna, a radio frequency receiver and a baseband processor;

[0063] A receiving antenna for receiving external wireless signals;

[0064] A radio frequency receiver for converting wireless signals into baseband signals;

[0065] The baseband processor is used to analyze the cyclic redundancy check information and load data from the baseband signal;

[0066] The retransmission processor is configured with operational instructions executable by the retransmission processor to perform the following operations:

[0067] Receive the cyclic redundancy check information and payload data in the multi-channel bluetooth receiving branch;

[0068] The step of judging the current working mode, the working mode includes the first mode...

Embodiment 3

[0087] An embodiment of the present invention provides an electronic device, and the electronic device includes the Bluetooth multi-channel receiving system described in Embodiment 2 of the present invention.

Abstract

An embodiment of the present invention provides a bluetooth multi-channel receiving method, which relates to the field of bluetooth communication. The method includes: receiving cyclic redundancy check information and load data in multiple bluetooth receiving branches; determining that the current working mode is the first mode or the second mode; in the first mode, according to the multi-channel The cyclic redundancy check information in the Bluetooth receiving branch determines whether the load data in the multi-channel Bluetooth receiving branch is retransmitted; in the second mode, according to the cyclic redundancy check in the multi-channel Bluetooth receiving branch The remaining check information and / or the payload data determine whether the payload data in the multi-channel Bluetooth receiving branch is retransmitted; and the output data is filtered out from the payload data that is not to be retransmitted. The invention also provides a bluetooth multi-channel receiving system and electronic equipment. Effectively reduce the number of retransmissions of the Bluetooth system to improve communication efficiency and complete high-quality and reliable Bluetooth information transmission.

Description

technical field [0001] The invention relates to bluetooth communication technology, in particular to a bluetooth multi-channel receiving method, system and electronic equipment. Background technique [0002] The extensive development of Bluetooth technology has made Bluetooth products and services a part of people's lives, especially audio applications such as Bluetooth headsets and Bluetooth speakers have brought great convenience to people's lives. However, as people's requirements for audio performance, communication distance and communication reliability are getting higher and higher, Bluetooth technology designed with low cost and low power consumption as the goal has more and more shortcomings in communication distance and reliability. The audio transmission of Bluetooth mainly adopts the transmission technology without error correction coding, and the error automatic retransmission mechanism based on 16-bit cyclic redundancy check (CRC:Cyclic Redundancy Check). In mo...
