| 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。该方法采用了多比特量化与比特抽取相结合的量化方法以及用于宽间隔处理的改进的平移替代法。将该方法由浮点运算转换为定点运算后在可编程逻辑门陈列(field programmable gate array,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.A quantization algorithm,combing multi-bit quantization and reshaping operation,and a modified shift replace algorithm used to widen the FH sequences are included.A wide-gap FH sequences generator is realized on FPGA after it is converted from floating pointed operation to fixed pointed operation,and the generator has several advantages,including simple structure,low comple... |
