摘要
无线局域网是计算机通信系统中的一个重要的组成部分,具有传输速率高、安全保密性强、使用灵活方便等特点。扩频技术不仅具有很强的抗干扰性能,而且其多址功能、安全保密、抗多径干扰等功能也备受人们青睐,把扩频技术用于无线局网中.必将使无线局域网的整体性能大大提高,满足各种情况下对系统的要求。
Wireless LAN is an important part of computer communication system,which is characterized by high transmission spead, strong security and easy use. Spectrum spreading is quite attractive for not only its strong anti-jamming ability but also its multi-address functionality, security and performance of antimultipath interference. Using spectrum spreading technology in wireless LAN would result in great improvement of wireless LAN's overall perfotmance and thus meet the re quirements for the system under various conditions.
