摘　　要：采用DSP Builder开发工具,实现了一种正交调制的混沌通信系统。首先在Simulink里面进行功能时序仿真,然后在Modelsim里面进行RTL级仿真,最后在QuartusII里面分析系统资源占用和时序约束。硬件实现结果和计算机仿真结果相符,而且该硬件系统有很好的扩展性。DSP Builder,a powerful FPGA design tool,is utilized to realize a chaos-based communication system.First,the timing simulation is performed in Simulink.Then,RTL simulation is performed in Modelsim.Finally,resource consumption and timing restriction of the system are analyzed.The result of hardware realization is consistent with that of computer simulation.Also,the hardware system can be easily extended.
