Adaptive Sparse Transform for Wireless Sensor Network Data
Aiming at the change of sparse structure introduced by mobility of the wireless sensor network（WSN） nodes and noise in data transmission, an adaptive sparse transform method based on dictionary learning （DL）for WSN data was proposed. The optimum sparse basis can be adaptively constructed according t...
