This paper considers proposing the mathematical model and simulation mode of inter-satellite channel based on the reliability of inter-satellite communication system. The Monte Carlo method is adopted to develop the spread spectrum communication system of two consumers. In order to reduce the bit errors of inter-satellite communication, both spread spectrum communication technology and channel ...

Some short pseudo-random sequences are used in spread spectrum communications. If a cryptographically secure pseudo-random sequence is used, the communication becomes a cryptographic communication. Moreover, we propose to use another non secret communication and a secret spread spectrum communication with a high ratio to hide the secret communication.

Spread spectrum communication is a new theory and modulation technique, and different from the conventional communication system. A good correlation property and large linear period of Pseudo-random sequence is the basis of spread spectrum communication systems intern CDMA (code division multiple access communication systems). Out of several techniques to implement direct sequence spread Spectr...

-Chaotic system are unstable and a-periodic ,making them naturally difficult to identify and to predict .This nonlinear , unstable and a-periodic characteristics of chaotic signals has numerous features that make it attractive for communication use. This field of communication is termed as chaotic communication. Chaotic communication signals have large bandwidth and have low power spectrum dens...
