| 摘 要： | 本文讨论了卫星分组话音／数据综合的扩频时隙ＡＬＯＨＡ的性能，并认为该协议较适合于卫星分组话音／数据综合的通信网中，给出了在扩频多址干扰为改进型高斯分布和某一时隙用户数有限的前提下，系统吞吐量的近似解析表达式和平均时延表达式，这比通常的标准高斯分布和无限用户的假设更精确，模拟说明结果性能是优越的。

| Abstract: | This paper discusses the performance of spread spectrum slotted ALOHA of integrated packet voice/data of satellite.On the condition of improved GAUSSIAN MAI(Multiple Access Interfence)and finite user in a certain slot,the formula of system throughput and average delay are obtained. These formula are more accurate than those on the condition of standard GAUSSLAN MAI and infinite user.The simulation results indicat that the protocol performance is superior to ordinary protocol. |
