Abstract
A Bluetooth data packet processing method is disclosed. According to the Bluetooth data packet processing method, a standard Bluetooth baseband protocol is extended, so that a Bluetooth node can also support polar encoding/decoding based on compatibility with the standard Bluetooth protocol. When processing a Bluetooth data packet, the Bluetooth node may choose to perform polar encoding on the data packet by using an extended Bluetooth baseband protocol, to improve demodulation performance of a Bluetooth receiver, and improve an anti-interference capability of a Bluetooth system.
