Description

technical field [0001] The present invention relates to a device and method in the technical field of wireless communication, in particular to a timing synchronization device and a synchronization method based on symbol rate adaptive interpolation. Background technique [0002] With the development of science and technology and the advent of the era of information globalization, modern communication technology is developing in the direction of digitalization, high speed, and low power consumption. With the needs of multimedia applications, traditional wireless communication technologies such as Bluetooth, wireless local area network (WLAN) and ultra-wideband (UWB) can no longer meet the needs of users for high-speed wireless data transmission rates, and they cannot provide Gigabit Ethernet, high-definition multimedia Interface (HDMI) comparable data transfer rate. Therefore, the high-speed wireless communication system that can realize the transmission rate of Gigabit / s or ...
