Further combinatorial constructions for optimal frequency-hopping sequences

Frequency-hopping multiple-access (FHMA) spread spectrum communication systems employing multiple frequency shift keying as data modulation technique were investigated by Fuji-Hara, Miao and Mishima [10] from a combinatorial approach, where a correspondence between frequency-hopping sequences and partition-type cyclic difference packings was established, and several combinatorial constructions were provided for FHMA systems with a single optimal FH sequence. In this paper, by means of this correspondence, we describe more combinatorial constructions for such optimal FH sequences. As a consequence, more new infinite series of optimal FH sequences are obtained. Key words and phrases: combinatorial design, frequency-hopping sequence, optimal, partition-type cyclic difference packing, projective geometry.
