  • Method and architecture of synchronization of wireless communication system
    Patent number: 11825434
    Abstract: A method of synchronization of wireless communication system is provided. The method includes the following steps: receiving a symbol from a wireless communication system by a user equipment; detecting ISI-free region of the received symbol; setting an endpoint of a FFT window within the ISI-free region; detecting shifted primary control frequency and shifted secondary control frequency of the symbol; calculating ICFO based on the shifted primary control frequency and a primary control frequency; calculating secondary control frequency based on ICFO and shifted secondary control frequency; finding the preamble of a frame based on the secondary control frequency; and determining, based on the preamble, a start point of the frame.
