摘要:
为实时产生混沌噪声,设计了一种基于Tent映射双向耦合映象格子和“接收-拒 绝”法的混沌噪声产生器,将其由浮点运算转换为定点运算后在FPGA上实现。所实现的 混沌噪声产生器具有结构简单、运算复杂度低、资源占用少且易于控制等优点。性能测 试结果表明:混沌噪声产生器能够产生具有任意分布和平坦功率谱的混沌噪声,且随机性较 好。

Abstract:
To generate chaotic noise, a chaotic noise generator is desi gned based on Tent double way coupled map lattice and “acceptance rejection” . The generator is realized on FPGA after it is converted from floating poin ted operation to fixed pointed operation.The realized generator has adva ntages including simple structure, low complexity of algorithm, accounting for f ew resources and easy control. The results of performance test show that the generator can generate chaotic noise with arbitrary distribution, flat po wer spectrum and good randomicity.
