Abstract:
A k ind o f acknow ledgment- type Slotted-ALOHA-CDMA channe,l w hich is called ACK-ALOHA-CDMA channel by the auther, is stud ied in this paper. The channe lm ode l is g iven firstly. Then the in terference between subsy stem s is obta ined and the transm ission influence in subsystem s is discussed. F inally, detecting probability is obta ined. Sim ulation resu lts show that a sign ificant perform ance im provem ent can be gained by using acknow ledgment- type Slotted-ALOHA- CDMA channel in sate llite VSAT system s and rad io packed netw orks w ith low comp lex ity and h igh-bandw idth eff-i c iency.
