New Class of Low-hit-zone Frequency Hopping Sequence Set with Optimal Periodic Partial Correlation

In frequency-hopping (FH) spread spectrum communication system, the correlation window length may change adapting to the communication channel environments as a result of the hardware complexity or the limited synchronization time, and the FH sequences with optimal partial Hamming correlation (HC) play an important role for FH spread spectrum communication. New set of low-hit-zone (LHZ) FH sequence with optimal periodic partial HC is designed in this paper. Theoretical analysis and simulation results indicate that the designed LHZ FH sequence set is optimal for any correlation window length.
