A novel tracking technique for slow FH signal-DSG algorithm and realization
Zhiqiang Li, Bangning Zhang · 1999
A novel tracking technique for a slow frequency hopping (FH) spread spectrum signal is presented and analyzed. This approach is based on the utilization of additional "sync data" carrying information for FH signal tracking which is added to the digital data stream. Results are presented for several different tracking algorithms and a rough comparison with a standard early-late gate tracking loop is made. Realization of an advanced slow FH system that employs the DSG algorithm is also discussed.
