SIMULINK Simulation Implementation of DS/FH Hybrid Spread Spectrum Communication System

A Chaos-based Spread Spectrum Communication System

We describe the design and CMOS implementation of a baseband spread-spectrum communication system using chaotic signals for spreading digital data. The communication system uses a new chaotic modulation scheme called M-DCSK (Modified Differential Chaos Shift Keying). The M-DCSK scheme and its characteristics are analyzed for single user and multi user applications. Results from a VLSI implement...

Co-simulation of Hybrid Systems: Signal-Simulink

This article presents an approach to simulating hybrid systems. We show how a discrete controller that controls a continuous environment can be co-simulated with the environment (plant) using C-code generated automatically from mathematical models. This approach uses Signal with Simulink to model complex hybrid systems. The choices are motivated by the fact that Signal is a powerful tool for mo...

Channel Coding Simulation Research of Inter- Satellite Spread Spectrum Communication System

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 ...

Design of Spread - Spectrum Communication System Based on FPGA

Spread spectrum communication technology, compared with the conventional communication technology, has many characteristics, such as a low interception rate, strong anti-noise performance, noise immunity, information hiding and multiple access communication. Widely used in military communication and civil communication at present, it is the core technology in the third generation mobile communi...
