基于耦合映象格子的宽间隔跳频序列的FPGA实现
FPGA realization of wide-gap frequency hopping sequences based on coupled map lattice
摘要
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 complexity of algorithm, few resources and easy control. The results of performance testing show that the wide-gap FH sequences generated by the generator have wide hopping gap, good balance demands and hamming correlation property.关键词
