摘要
Abstract
A novel and efficient algorithm is proposed for frequency-selective fading channels to classify space-time block code(STBC) via Kolmogorov-Smirnov(K-S) test when a single antenna is employed at the receiver. The proposed algorithm exploits the discrimination features provided by the empirical cumulative distributions(CDFs) of the received signal and realizes STBC identification by two-sample K-S test of the distance between CDFs. The algorithm’ s performance is compared under the condition of different modulation mode,sampling factors and confidence interval. Monte Carlo simulations demonstrate the good performance of the proposed algorithm,and the probability of correct identification is more than 90 percent when signal-to-noise ratio(SNR) is 6 dB above. The algorithm is well-suited for non-cooperative communications.关键词
