Abstract

Signal identification’ s intrinsic application is in the military field, where the detection, analysis and identification of unknown signals from potentially hostile communication sources is a vital task in signal interception, radio surveillance, interference identification and mitigation, and electronic warfare. So Signal identification has continued to be a major part of intelligent radios employed in military wireless communications up to present. With the deployment of the MIMO, new and challenging Signal identification problems have emerged, which did not exist for single antenna systems. An example of identifying these types of signals is identifying the space-time block (STBC) code in the MIMO-OFDM system. MIMO-OFDM systems have different types, three of which are identified in this paper. These three types of systems include SM-OFDM, AL-OFDM, STC3-OFDM. Previously, these three types of systems were identified by the second-order moment of the signal method. In this paper, this identification is performed by the second-order rotating stationarity of the signal. This method can perform better in lower SNRs. In addition, the proposed method provides good performance with low sensitivity to time offset and channel conditions.
