In this paper, we investigate the construction of error estimating codes and propose a content-based error estimation coding framework(CBEEC). The CBEEC captures the bur sty nature of channel errors and provides a better estimation than that of EEC proposed by Chen et.al. Specifically, the core technique of the CBEEC is that each bit of a group is chosen consecutively from the original data bits and...
The Intrinsic Mode Functions (IMFS) decomposed by Empirical Mode Decomposition (EMD) often lose their physical meaning because of the unconventional data and noise. An improved EMD method based on Singular Value Decomposition (SVD) diagnosed of attractor was introduced. The SNR was improved and the decomposed component was given its meaning by this method. The original signal was diagnosed by SVD...
