Abstract: The frequency hopped spread spectrum waveform is commonly used by communications systems for its ability to combat intentional jamming and its inherent diversity. It can therefore be expected that these systems will be required to operate in jamming and fading environments. Since synchronization is a vital aspect of spread spectrum communications, it is important to predict synchronization performance in such adverse environments.;Several schemes for the acquisition and tracking of frequency hopped signals are discussed. Formulas for describing system performance in terms of detection reliability, acquisition time and mean time to loss of lock are presented. Mathematical models characterizing the interference and multipath fading channel are developed. The performance of some example systems, with application to particular environments, is then analysed and results computed.
