Embodiment Construction
[0028] In order to make the invention, the present invention will be described in detail below with reference to the accompanying drawings and techniques.
[0029] In the embodiment of the present invention, there is provided an empty time-related matrix blind recognition method, see figure 1 As shown, it includes the following:
[0030] S101, the signal is received through the synchronous sampling of the transmitting end and the receiving end in the communication system, and the received signal is pre-processed, and several groups receive signal samples;
[0031] S102, set the range of delayed values, and calculate an empty time-related matrix corresponding to each group receive signal samples under each delay in the range of the delay.
[0032] S103, the white-proof processing of the elements in the correlation matrix in the correlation signal samples in the correlation signal sample, and constructs an empty time-based group code feature vector by calculating the frobenis norm o...
