Cryptography-Based Medical Signal Securing Using Improved Variation Mode Decomposition with Machine Learning Techniques

Algorithm 1

: For Adaptive Kalman Filter.

	function [x_aposteriori P_aposteriori] = KalmanFilterIteration(z,Q,R,x_aposteriori_last, P_aposteriori_last)
	x_apriori = x_aposteriori_last;
	P_apriori = P_aposteriori_last + Q;
	K = P_apriori/(P_apriori + R);
	x_aposteriori = x_apriori + K (z - x_apriori);
	P_aposteriori = (eye(length(x_aposteriori)) - K) P_apriori;
