| Abstract: |
| 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. |
