Abstract

The invention provides a wireless Bluetooth on-ear voice communication system with channel coding, including a smart wireless device, wherein the Bluetooth master device includes a first Bluetooth chip, configured to establish a SCO link / CSB link / ACL link, channel-encode the data of the SCO link / CSB link / ACL link, and transmit the encoded data to the Bluetooth physical layer for transmission; theBluetooth slave device includes a second Bluetooth chip, configured to establish a SCO link / CSB link / ACL link, wherein the Bluetooth physical layer of the second Bluetooth chip receives the data of the encoded SCO link / CSB link / ACL link sent by the Bluetooth physical layer of the first Bluetooth chip, and performs channel decoding on the received data of the encoded SCO link / CSB link / ACL link. Theinvention improves the Bluetooth protocol between the master device and the slave device, and channel coding and decoding is adopted for the data to be transmitted in the subsystem formed by the master device and the slave device, thereby improving the reliability of the entire audio data transmission.

Description

technical field [0001] The invention relates to the technical field of bluetooth communication, in particular to a wireless bluetooth ear-to-ear voice communication system and communication method with channel coding. Background technique [0002] With people's pursuit of wireless life, audio equipment such as wireless earphones and wireless speakers have entered ordinary families. As the most popular wireless connection method, Bluetooth is used in wireless earphones and wireless speakers. Not only get rid of the shackles of wires between smart devices (such as smart phones, personal computers, laptops, etc.) It can also get rid of the shackles of wires and realize true wireless connection. [0003] In the existing wireless bluetooth voice communication system, voice communication is generally realized through a synchronous link (SCO) between the primary and secondary earphones. Because there is a head barrier between the main and auxiliary earphones, and if there is an ...
