Constructions of optimal low hit zone frequency hopping sequence sets with large family size

<p style='text-indent:20px;'>Frequency hopping sequences with low hit zone is significant for application in quasi synchronous multiple-access systems. In this paper, we obtained two constructions of optimal frequency sequence sets based on interleaving techniques. The presented are new and flexible parameters large family size which can meet the needs practical applications. Moreover, all proposed cyclically inequivalent. Some constructed literatures included our family. contributed quasi-synchronous multiple access system to reduce or eliminate interference.</p>
