In this paper, the authors present an approach that enables the receiver to identify the WiMAX standard among different systems employing the OFDM technique (Orthogonal Frequency Division Multiplexing) consisting of large number of mutually orthogonal sub carriers. This characteristic provides high robustness against multipath effects. The approach is one of the new algorithms introduced recently to discuss the OFDM systems identification problem. Although this algorithm reflects good performance in term of correct classification, it still suffers from some limitations when identifying some standard such as WiMAX.
