Abstract A novel and efficient algorithm is proposed for Space-Time Block Code (STBC) classification, when a single antenna is employed at the receiver. The algorithm exploits the discriminating features provided by the forth-order cumulants of the received signals. Higher-order cumulants (of order greater than 2) are used to eliminate the impact of noise. Firstly, the theoretical value of the different STBCs is caculated, then the samples of STBCs are classified with an interval detector. It does not require estimation of the channel information and signal-to-noise ratio of the transmitted signal. Simulation results show that the proposed method for blind recognition of STBC achieves good performance.
