| Abstract: |
| To improve the efficiency of frequency-hopping(FH) communication network, FH-seq
uence phase-shifting is used to build FH communication network. First, the theor
y and method of sequence phase-shifting is analysed based on the m sequence. Sec
ond, the networking process and protocol are expounded in great detail while the
system is divided into control channel and data flow channel. And a method is p
roposed to optimize the phase-shifting value.Such advantages as flexibility in n
etwork control, high efficiency and powerful anti-jamming performance are shown
for the new designed network. The simulation results show that sequence phase-sh
ifting FH communication network possesses a low inter-network interference
compared with asynchronous network. |
