Abstract :
In this paper, the nonorthogonal multilevel spread ALOHA system, which combines the spread ALOHA system with the nonorthogonal multilevel system is investigated. In particular, the throughput performance of the nonorthogonal multilevel spread ALOHA system is evaluated by theoretical analysis. It is found that the throughput performance of the nonorthogonal multilevel spread ALOHA system is greater than that of the conventional spread ALOHA systems when the network traffic is not busy. It is found that application of the traffic control to the nonorthogonal multilevel spread ALOHA system is effective in improvement of the performance.
