| 摘 要： | 为实时产生宽间隔跳频序列，提出了一种基于Tent映射的双向耦合映象格子的宽间隔跳频序列产生方法，采用了多比特量化、比特抽取法和改进的平移替代法。将该方法由浮点运算转换为定点运算后在FPGA上实现，所实现的宽间隔跳频序列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：宽间隔跳频序列产生器产生的跳频序列具有宽的跳频间隔、良好的平衡性和汉明相关性。

| Abstract: | To generate wide-gap frequency hopping(FH) sequences in real-time,a generator based on Tent double-way coupled map lattice is presented.Multi-bit quantization,reshaping operation and a modified shift replace algorithm are included.A wide-gap FH sequences generator is realized on FPGA after it is converted from floating pointed operation to fixed pointed operation,the generator has several advantages including simple structure,low complexity of algorithm,few resources and easy control.The results of performa... |
