Discrete tracking system for slow FH. II. Algorithms with concentrated synchronization group

For pt.I see ibid., vol.39, no.2, p.304 (1991). A novel algorithm for discrete tracking of slow frequency hopping spread-spectrum signals is described and analyzed. In this system, each Mth hopping interval is completely used for transmission of synchronization data. The motivation for introducing this algorithm is that it allows a large degree of flexibility with respect to trading off system performance, complexity, and the redundancy introduced for tracking purposes. The analysis of the system performance is based on the utilization of results from discrete renewal process theory. However, because of the difficulty in obtaining the exact values for the transition probabilities, approximate results are presented.
