Abstract

We proposed a one-step method for blind identification of MIMO signal in noncooperation communication, when assuming that the unknown source was one of the four typical types of signal in wireless communication, i.e. MIMO signal, single user single antenna signal, virtual MIMO signal and multibeam smart antenna signal. In this method, we need to stack the oversampling signals at each element of the receiver first, and then blindly estimate the DOAs and delays of the stacked signal employing JADE-MUSIC algorithm. Simulation results show the feasibility of this method. The result of this paper has important value in both theory and application.
