Detecting the signals of a MIMO communication system in condition of unknown fading channels,small samples,and low SNR is a challenging task.An uncooperative communication detection solution is proposed in this paper to estimate the uncooperative communication parameters of MIMO communication systems.Firstly,a simulation platform is constructed for MIMO communication systems.Secondly,some key technologies are researched,such as coding mode recognition,blind channel estimation,and modulation type recognition.In addition,improvement and implementation of the technologies are described.Finally,performance of the proposed solution is tested through simulation,and the potential application fields of the solution are discussed.
