Abstract: In this paper, the work is mainly concentrated on removing non-linear parameters to make the physiological signals more linear and reducing the complexity of the signals. This paper discusses three different types of techniques that can be successfully utilised to remove non-linear parameters in EEG and ECG. (i) Transformation technique using Discrete Walsh-Hadamard Transform (DWHT); (ii) application of fuzzy logic control and (iii) building the Adaptive Neuro-Fuzzy Inference System (ANFIS) model for fuzzy. This work has been inspired by the need to arrive at an efficient, simple, accurate and quicker method for analysis of bio-signal.

Keywords: electroencephalograms; EEG; electrocardiograms; ECG; wireless BCI; discrete Walsh Hadamard transform; DWHT; fuzzy logic; ANFIS; brain-computer interface; nonlinearity; biosignals; nonlinear parameters; fuzzy control; adaptive neuro-fuzzy inference system; neural networks.
