Embodiment 1

[0023] Such as figure 1 As shown, the present embodiment proposes a Bluetooth multi-channel receiving method, the method comprising:

[0024] S101. Receive cyclic redundancy check information and payload data in multiple bluetooth receiving branches.

[0025] 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

[0060] 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;

[0061] A receiving antenna for receiving external wireless signals;

[0062] A radio frequency receiver for converting wireless signals into baseband signals;

[0063] The baseband processor is used to analyze the cyclic redundancy check information and load data from the baseband signal;

[0064] The retransmission processor is configured with operational instructions executable by the retransmission processor to perform the following operations:

[0065] Receive the cyclic redundancy check information and payload data in the multi-channel bluetooth receiving branch;

[0066] The step of judging the current working mode, the working mode includes the first mode...

Embodiment 3

[0085] 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

The embodiment of the invention provides a Bluetooth multi-channel receiving method, and relates to the field of Bluetooth communication. The method comprises the following steps: receiving cyclic redundancy check information and load data of each Bluetooth receiving branch in multiple Bluetooth receiving branches; in one mode, when the cyclic redundancy check information in at least one Bluetoothreceiving branch is correct, determining that retransmission is not carried out. The invention further provides a Bluetooth multi-channel receiving system and electronic equipment. The number of times of retransmission of the Bluetooth system is effectively reduced, so the communication efficiency is improved, and high-quality and reliable Bluetooth information transmission is completed.

Description

[0001] The present invention is a divisional application of a Chinese invention patent application with an application date of February 09, 2018, a patent application number of 201810136533.0, and an invention title of "A Bluetooth multi-channel receiving method, system and electronic device". technical field [0002] The invention relates to bluetooth communication technology, in particular to a bluetooth multi-channel receiving method, system and electronic equipment.
