# Lyapunov exponent calculation using MATLAB - open to bidding

Dear Ognjen011

Would you like to join with me in helping one student who wish to process ECG data using Lyapunov exponent , and then do some encryption work

we need to do the following

1. Get Chaotic Signal

For this provide me some samples of signals with acquisition rate known for signal analysis

2. Checking the signal for it is chaotic or not state space diagram.

I need your algorithm for this step

3. Then find the Largest Lyapnov Exponent.(λ)

I need your algorithm for this step

4. Obtaining Random sequence by using Chaotic mapping( Logistic map or Henon Map)

I need your algorithm for this step

5. The Value of λ is used to calculate henon map X and Y

6. These values are used to encrypt ECG signal using some suitable Data Encirption Standard or Advanced Encryption Standard.

what you have decided for this step, I need your algorithm for this step

7. Then final getting Encrypted ECG signal.

Beceriler: Algoritma, Matematik, Matlab ve Mathematica

In my opinion, a chaotic signal means if the signal can be represented by deterministic equation. Then to know whether it is chaotic find correlation dimension, entropy and lypunov exponent. Lypunov exponent can be fi Daha Fazla
