| Abstract_FL | Stagewise Orthogonal Matching Pursuit(StOMP algorithm has rapid computing speed and small amount of calculation quantity,and is thus highly suited to the reconstruction of Wireless Sensor Network (WSN) Compressed Sensing (CS) data.The influence of threshold selection of StOMP algorithm on the reconstruction accuracy of CS data in WSN is analyzed and studied.And this paper proposes an adaptive adjustment method of threshold value in the StOMP algorithm.Based on the idea of Proportional-Integral-Derivative (PID) method,the adjustment value of the threshold is calculated according to the reconstruction error.Reconstruct the data with the new threshold,and this process is repeated to improve the accuracy of reconstruction.Experimental result shows that this method can quickly find the threshold value which meets the error requirement and has distinctly improved reconstruction precision compared with the adjustment method of fixed threshold value. |
