摘要

CDMA可以在无线环境中提供显著的优势，特别是当必须支持大容量和宽范围的服务速率时。本文提出了一种cdma开槽ALOHA系统，该系统中所有发射机都使用相同的PN序列，但芯片相位不同，由于PN序列的自相关特性，可以捕获和接收数据包。然后对其信道吞吐量进行了分析。分析和仿真结果表明，该系统的最大信道吞吐量远高于纯S-ALOHA系统，能够在保证QoS的情况下支持多业务。

A CDMA-slotted ALOHA broadband system for multiservices

CDMA can offer significant advantages in wireless environments, especially when large capacity and wide range of service rates must be supported. This paper proposed a CDMA-slotted ALOHA system, in which all transmitters used the same PN sequence but with different chip phases and packets can be captured and received because of the autocorrelation property of the PN sequence. Then its channel throughput is analyzed. Analysis and simulation results show that the maximum channel throughput of this system is much greater than pure S-ALOHA system and multiservices can be supported with guaranteed QoS.
