Abstract: The mobile-cellular model for weapon cooperation data link (WCDL) is proposed. The frequency hopping/code division multiple access (FH/CDMA) for this model is studied based on discrete frequency division multiplexing (FDM). Theoretically, the multiple access technology can sustain the service for infinite users and provide low delay service. The performances of success rate, throughput, and delay are analyzed. The influences of the main parameters such as the number of channels and the gain of spreading spectrum are simulated. The results demonstrale that the multiple access technology can meet the low delay application request of WCDL with better performances.
