- W4288388622 abstract "Feature extraction-based methods are frequently used for driving behavior recognition systems using the fine-grained CSI from the PHY layer. However, we discover a jump phenomenon: there are switches of frequency-selected fading in random individual time slots, called jump points. Moreover, the jump phenomenon causes the extracted feature values to be inaccurate, resulting in erroneous behavior classification. In this paper, to eliminate the effects of the jump phenomenon, the Pearson correlation coefficient is introduced to detect the position of jump points. Meanwhile, by transforming this problem as an optimization problem, we propose a similarity calculation model and introduce a nested switch-mode firefly algorithm to correct the jump point. The method is tested by the experiments conducted in three indoor scenarios. The results indicate that the proposed method can effectively solve the problem caused by the jump phenomenon and improve the stability of eigenvalues." @default.
