New near-optimal frequency-Hopping sequences of length pq
Yun Kyoung Han, Kyeongcheol Yang · 2008
In this paper we construct near-optimal frequency-hopping sequences whose maximum Hamming autocorrelation is given by λopt+ 1 where λoptis the optimal Hamming autocorrelation value with respect to the Lempel-Greenberger bound. Their period, frequency set size, and maximum Hamming autocorrelation are given as pq, m and pq−1/m + 1, respectively, where p and q are distinct odd primes, and m is an even common divisor of p − 1 and q − 1.
