This paper proposes a joint empirical mode decomposition and singular spectrum analysis based pre-processing method for performing the blood glucose estimation. Here, both the near infrared signals and the electrocardiogram signal are acquired from a wearable non-invasive blood glucose estimation device. For the empirical mode decomposition based pre-processing method, the intrinsic mode functions are selected based on the correlations between the intrinsic mode functions and the acquired near i...

This study proposes an augmented Lagrange multiplier-based method to perform the singular spectral analysis-based denoising without computing the singular values. In particular, the one-dimensional (1D) signal is first mapped to a trajectory matrix using the window length L . Second, the trajectory matrix is represented as the sum of the signal dominant matrix and the noise-dominant matrix. The determination of these two matrices is formulated as an optimisation problem with the objective functi...

This study proposes a computer cryptographic system through performing the chaotic modulation on the intrinsic mode functions with a non-dyadic number of the encrypted signals. First, the empirical mode decomposition is applied to an input signal to generate a set of intrinsic mode functions. Then, these intrinsic mode functions are categorised into two groups of signals. Next, a type 1 polyphase is employed to represent each group of signals. These polyphase components are combined to generate ...
