Detecting Probability and Throughput of VSAT Systems Based on ACK-ALOHA-CDMA Channel
Jianhua Shao, Kuixi Yin, Xinghe Wang, Hua Zhao · 2008
A new kind of acknowledgment-type slotted-ALOHA-CDMA channel for multiple code spread spectrum, which can be used for uplink channel of VSAT systems, is studied for the first time in this paper. The channel model is developed firstly. Then the interference between subsystems is obtained and the transmission influence in subsystems is discussed. At last, detecting probability and throughput is calculated. Numerical results show that a significant performance improvement can be gained by using ACK-ALOHA-CDMA channel in satellite VSAT systems.
