Synchronization signal detection method and device, equipment and storage medium

The invention discloses a synchronization signal detection method, device and equipment and a storage medium, and the method comprises the steps: carrying out the down-sampling of a subframe signal under the condition of receiving the subframe signal sent by a base station, and obtaining a sampled information flow; segmenting the sampled information flow into a preset number of subsequences; performing convolution calculation on each sub-sequence, and combining convolution results of convolution to obtain a cross-correlation result of orthogonal frequency division multiplexing symbols of the information flow and the local synchronization signal; calculating an average value of the cross-correlation values of the subframes, and obtaining a peak value of the average value; and under the condition that the peak value exceeds a threshold value, determining that the synchronization signal is received. 本申请公开了一种同步信号检测的方法、装置、设备及存储介质，该方法包括：在接收基站发送的子帧信号的情况下，对所述子帧信号进行降采样，得到采样后的信息流；将所述采样后的信息流分割为预设个数的子序列；针对各所述子序列进行卷积计算，并组
