Wide-gap Frequency Hopping Sequences Based on Tent Double Coupled Map Lattice and its Performance Analysis

To generate wide-gap frequency hopping (FH) sequences in real-time, a generation way of wide-gap FH sequences based on Tent Double-way Coupled Map L at ti ce in real-time is presented. A quantization algorithm, combing multi-bit quan ti zation and reshaping operation, and a modified shift replace algorithm are used to widen the FH sequences.Simulation results show that the wide-gap FH sequence s in real-time obey the uniform distribution with wide hopping gap, good hamming correlation property and complicated phase space.
