A Method for Blind Identification of Uplink Virtual MIMO Signal

This paper discusses system models of three types of signal in wireless communication, i.e. single user single antenna signal, virtual MIMO signal and single user MIMO signal. Based on the model, proposes a method for blind identification of uplink virtual MIMO signal by using the MUSIC algorithm to blindly estimate DOAs of the received signal. Simulation results show the feasibility of this method. This approach has important value in both theory and application for noncooperation communication environment.
