摘要
采用补偿码键控(ＣＣＫ)可以使ＩＥＥＥ ８０２．１１ｂ无线局域网系统实现多速率通信,这是补偿码第一次用于调制。介绍了无线局域网的直接序列扩频(ＤＳＳＳ)的各种模式,着重介绍了无线局域网所采用的ＣＣＫ调制方式,并对ＣＣＫ调制的性能进行了理论上的分析。
Adopting CCK technologycan make IEEE 802.11b wireless LANsystem realize multiple-rate communi-cation, which is the first time for com-pensation code being used in modula-tion. All modes of DSSS in wirelessLAN is introdced. CCK modulationmode adopted in wireless LAN is intro-duced in detail.Theoretic analsis onfeatures of CCK modulation is also giv-en.
