摘　　要：对多个码分信道情况下扩频多址ALOHA(additivelinkon-linehawaisysetm)系统的吞吐性能进行了深入研究,并与单个码分信道时的扩频ALOHA系统以及传统ALOHA系统进行了吞吐量性能的比较,给出了相应的仿真和数值结果。结果表明,多码道扩频多址ALOHA系统可以显著提高网络的吞吐性能,在低复杂度和高信道利用率的无线分组网络应用中具有重要意义。The performance of throughput for multiple code-channel spread spectrum multiple access ALOHA (MC-SSMA ALOHA) systems is studied. The comparisons for the throughput between MC-SSMA ALOHA and single code-channel SSMA ALOHA, and conventional ALOHA are also made. Numerical results show that a significant performance improvement can be gained by using MC-SSMA ALOHA in radio packet networks with low-complexity and high-bandwidth efficiency.
