基于压缩感知的数据压缩与检测
Data Compression and Detection Based on Compressive Sensing
摘要
Abstract
In wireless sensor networks,signal is sampled and reconstructed using the technology of Nyquist in the past. But it requires a substantial increase in the cost with the growth of the signal frequency,which is that people do not like to see. Recently a new technology is emerged,which is called compressive sensing technology. Compressive sensing can use less data and appropriate reconstruction method to get a more accurate original signal. Put Sparse Bayesian Learning ( SBL) and compressive sensing together to form a better way of re-constructing compressible signal under the noise. This method can effectively control the dimension of measurement data within the range of allowed error in WSN,so you can ensure a certain degree of error while reducing the cost,improving the efficiency of the algorithm.关键词
