摘要

无线通信服务在未来可能由比今天提供服务的更多的运营商提供。一个关键的促成因素是自动共享无线电频谱的可能性。带宽效率的定义是一个基站在给定的频谱中可以支持的用户数量。研究了两运营商共享同一频谱时DS-CDMA和跳频系统的带宽效率。研究了基站位置的影响。结果表明，DS-CDMA系统的损耗较大，而跳频系统的损耗较低。

On the performance of coexisting spread spectrum systems

Wireless communication services may in the future be provided by a larger number of operators than provide the services today. A key enabling factor is the possibility to automatically share the radio spectrum. Bandwidth efficiency is defined as the number of users that can be supported by a base station in a given spectrum. The bandwidth efficiency in a DS-CDMA and a frequency hopping system is studied when two operators share the same spectrum. The influence of base station location is also studied. The results indicate a substantial loss for the DS-CDMA system and a lower loss for the frequency hopping system.
