  • In order to solve the intra-class blind recognition problem of IFFT-based multi-carrier modulation signals under the conditions of multi-path fading background, a blind identification algorithm of multi-carrier modulation signal is proposed based on singular value decomposition of structural matrix. Without any prior knowledge of data information as well as the type and length of spreading code, this algorithm can determine the type of multi-carrier modulation signal accurately according to the number of larger non-zero singular value of structural matrix in accordance with simple criteria, and have achieved good results. It does not have to design the complexity classifier in the traditional recognition algorithm after feature extraction, and simplifies the recognition process. Both the theoretical analysis and simulation results verifie the correctness and effectiveness of the algorithm, therefore ,the algorithm has certain theoretical and practical reference value.
