| Abstract(in English) | In this paper, the nonorthogonal Code Shift Keying(CSK) ALOHA with received-power adaptive access control scheme is investigated and evaluated. In our system, a user who is ready to send senses the received power from other users, and then the user decides whether to transmit or refrain from transmission according to the received power and a pre-decided threshold. Not only overcoming the MAI problems, but our system also improve the throughput performance. The throughput performance of the proposed system is evaluated by theoretical analysis. In particular, the throughput performance is analyzed in consideration of free space loss. Consequently, it is found that the access control scheme has high affinty with the nonorthogonal CSK ALOHA system. |
