Abstract
Considering that the application of the direct-sequence slotted spread ALOHA communications system to the access/control channel is effective in communications systems with traffic channels operating at CDMA mode, the spread ALOHA communications system is discussed in terms of the system configuration and throughput performance. The throughput performance of the spread ALOHA communications system using a unified spread code is derived by means of two methods. One is based on the simulation of demodulation algorithm, and the other is based on the approximation by simple modeling. The modeling consists of two main conditions depending on the collision of packet signals. It becomes obvious from quantitative evaluation that the approximated results coincide with the simulated results, and that the modeling is very effective to evaluate the throughput performance of the spread ALOHA communications system.
