Comments on "Code acquisition for a frequency-hopping system

For the original article see ibid., vol.COM-35, no.5, p.566-8 (1987). It is pointed out that in the paper by I. Vajda and G. Einarsson the proposed sets of frequency-hopping sequences, that permit the correct resynchronization in FH-MFSK (frequency-hopping multiple-frequency-shift-keyed) multiple-access systems, are only the special case of the Reed-Solomon sets of asynchronous frequency-hopping sequences previously derived. For the case when the number of available frequencies is prime, another class of FH-MFSK sequences with good resynchronization and interference properties is presented.
