The embodiment of the invention belongs to the technical field of communication, and designs a user blind detection method in an ad hoc network. The method comprises the following steps: carrying out cyclic prefix removal and Fourier transform processing on received data of each receiving antenna; performing channel estimation on the frequency domain signal through a DMRS port to obtain a channel estimation result; estimating and compensating the CSD by using the channel estimation result to compensate the windowing deviation of the received data, so that the phase of the received data is aligned with the phase of the local signal; carrying out merging operation on the received data of different receiving antennas, and carrying out cross-correlation on the merged received data and a local signal to obtain a cross-correlation value; traversing the possible mask sequence of the DMRS port, and repeating the operation from channel estimation on the frequency domain signal through the DMRS port to calculation to o
