- In this paper, a Code Shift Keying ALOHA (CSK ALOHA) system with dual-spreading sequences is proposed. The dual-spreading sequence is generated by multiplying the outer sequence by the inner sequence. The M-sequence is used for the inner sequence and the orthogonal sequence set is employed for the outer sequence. The throughput performance is analyzed and the proposed system is compared with the conventional systems. As a result, it is shown that the proposed system outperforms the DS ALOHA system. Moreover, the maximum throughput performance of the proposed system is better than that of the CSK ALOHA system with orthogonal sequence set.
