Hi all friends.I hope someone can help me about chaotic communication.I am a master student and studying chaotic communication and its modulation techniques especially in Matlab.Please is there anybody here to give me ebook or something else.(maybe documents..)about Chaotic communication and modulation types such as (CSK,DCSK.... for Matlab).I will be pleased.And I really need. Thanks now..
 

Re: with pleasure :)

Hi my friend,chaotic communication is new technique and recently this is mostly studied topic in communication area because of it provides more security by using
chaotic signals that are wideband and aperiodic waveforms.In this communication type chaotic signals are used as carriers,probably you know from standard analog and digital communication.And we obtain easily chaotic signals from basic electronic circuit..And if you really interested cahotic communication, I can send you some documents related with this topic.But you guess that I am still studying and I am keenly learn something more about it.What about you my friend?And what is your situation now?
my email is : hitx_47@hotmail.com

I am waiting your response..
Byes.

Hi,
Thanx for the info..But, in what way this is different from spread spectrum communications? Does the BW required to transmit a chaotic signal will be more?How the receiver will be able to extract the wanted signal?
kindly clarify...
 

Hi again, as I said before I am still new in this topic
and still studying about chaotic communication.Definetely,it must be a little different
from other communications such as modulatiom types and sometimes does not need to be synchronized. To obtain original message coherent or non coherent detection method(used in poor propogation medium and synchr. can not be necessary).And now I really need CSK(Chaos Shift Keying) in matlab or simulink model. CSK is one of modulation technique in this communication type.I am always searching simulation of CSK in simulink in Internet but I have not found yet.So can you help me about it?Thanks again..

hi my friend i think we should link up i am also doing chaos pls can you email me your documents so that maybe we can share notes..

I am a masters student..
 

Hi Hitx and everybody!
I am a student and studying chaotic communication and its modulation technique.
I am searching simulation of CSK in simulink in Internet and i found your questions in https://search.edaboard.com.
Your research about it in 2008, so can you help me about it? I am really need, because I have many problems and I do not know what I will do with it !
I hope to have a reply from you!
My email is saodoingoi13292@yahoo.com
Thank you very much!
 

hi, chaotic signals are highly random deterministic signals, they can be generated by simple electronic oscillator circuit(eg:- collpits oscilator), they are uged in communication there main advantage is that it is highly random so that it provides high level security for the data,and also it has a property os synchronization which helps in proper retreval of data at the reciever side.

hi everyone, i 'm studying in chaotic signal but i have many problem.
I use labview to simulate DCSK( Differential chaos shift keying), CSK( chaos shift keying) but it does not finish, i hope you will support me. thank a lot!
