- 概要
- In this paper, a MPPM DS/SS ALOHA system is proposed. In the MPPM DS/SS ALOHA system, information data are represented by combining the slot position of several spreading codes in a packet. Therefore, the number of symbols per packet of the DS/SS ALOHA system is smaller than that of DS/SS ALOHA system and interference can be reduced. In this paper, the throughput performance is evaluated in the MPPM DS/SS ALOHA system. The throughput of the MPPM DS/SS ALOHA system is higher than that of the DS/SS ALOHA system.
