The present invention provides a frame synchronization method, device, electronic equipment and storage medium. The method includes: based on N channels of sinusoidal signals with different frequencies, respectively performing frequency offset correction on received signals to obtain N channels of corrected signals; is a positive integer greater than 1; determine the frame header position of each channel of the corrected signal, and determine the frame synchronization error corresponding to each channel of the corrected signal according to the frame header position; select the one with the smallest frame synchronization error One of the corrected signals is used as a frame synchronization output signal to complete frame synchronization. Therefore, a wide range of frequency offset correction can be achieved and frame synchronization can be accurately completed. Compared with the traditional frequency domain equalization algorithm, the frequency offset can be corrected before the frame synchronization, and the corrected frequency offset range is larger, which can adapt to a harsher communication environment.
Description
technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a frame synchronization method, an apparatus, an electronic device and a storage medium. Background technique [0002] With the development of communication technology, communication technology is gradually developing in the direction of high-speed and long-distance wireless communication. However, with the increase of communication rate, the interference from the external environment will become stronger and stronger under the condition of wireless channel. Among them, multipath The intersymbol interference caused by the effect has a particularly obvious influence on the communication capability of the wireless system. Therefore, suppressing the intersymbol interference has become an important topic in the field of wireless communication. [0003] The systems for suppressing inter-symbol crosstalk can be mainly divided into two types: single-carrier and mul...
