“…Annovazzi-Lodi et al (1996, 1997 proposed a method of CSK using semiconductor lasers with optical feedback. Also studies on chaotic communications based on CSK in various laser systems have been reported Davis et al 2001;Mirasso et al 2002). Almost all these systems used chaotic oscillations in class B lasers, such as solid-state lasers, fiber lasers, and semiconductor lasers.…”

“…However, it is assumed to be CMA as long as the modulation amplitude of a message is (1996) proposed a CSK system in semiconductor lasers with optical feedback using systems consisting of a single chaotic transmitter and two chaotic receivers. Mirasso et al (2002) also proposed a CSK system using a single chaotic generator of a semiconductor laser with optical feedback both for a transmitter and a receiver. They numerically demonstrated data transmissions of a bit rate of 2 Gbps.…”

Chaotic data encoding or scrambling is a technology for overcoming the difficulties of the digital methods in secure communications. Using chaotic lasers as light sources, high-speed and broadband secure communications can be established. In this chapter, we discuss cryptographic applications of chaos in semiconductor lasers. The technique we treat in this chapter is an analog chaotic encryption and decryption. Messages to be sent are encoded into chaotic time series generated from a chaotic semiconductor laser and decoded by a chaotic laser with the same characteristics. The key for chaos communications is chaos synchronization, which we discussed in the previous chapter. In chaotic communications, a small message is embedded into a chaotic laser carrier and the total signal is sent to the receiver. Only the chaotic oscillation is reproduced based on chaos synchronization and a chaos-pass filtering effect in the receiver laser. By subtracting the receiver output from the transmission signal, the message is successfully decoded. Message Encryption in a Chaotic Carrier and Its Decryption Chaotic CommunicationsThe development of efficient technologies for high-speed and massive data transmissions is an urgent subject in the rapidly growing information-oriented society. One of the important issues of information and communication networks is the security problem. In secure data transmissions, a message to be sent is usually encoded by computer software and the security of encoding is guaranteed by the complexity of the calculations necessary to decode the original message. However, the development of digital computer technology is so fast that the standard code for scrambling data in secure communication systems can be soon decoded by a fast computer. On the other hand, the enhancement of the complexity of calculations for encoding and decoding messages may lose real-time processing of data transmissions. In the meantime, J.

This paper deals with the theory of multi-user chaos shift keying communication systems in the coherent case and in particular with bit error performance under near optimal demodulation. The new approximated likelihood and near optimal demodulator is based on the statistical likelihood of the received signal and is a theoretical generalization of the conventional correlation demodulator involving autocorrelations of the spreading. Near optimal theoretical results beginning from an exact analysis are derived for the bit error rate of a typical user; there is emphasis on their structure in regard to separating the effects of channel noise and interference from other users, and in comparison with single-user results. The new demodulator is shown under particular assumptions to be a form of rake demodulator in the sense that it involves autocorrelation-like terms at various lags. The results are illustrated by theoretical calculations and numerical simulations which point out the enhanced performance of the near optimal demodulator relative to the correlation demodulator.
