摘　　要：阐述目前无线局域网的特点和主要传输方式及扩频通信的主要工作原理,并就直接序列扩频、跳频扩频、跳时扩频和脉冲线形扩频四种扩频技术工作原理、扩频技术的四大特点、扩频抗干扰技术和扩频技术在无线局域网中的应用前景等作了讨论,以供相关科研工作人员参考。This thesis attempts to introduce the characteristics and the main transmission modes of the wireless local area network （WLAN） nowadays. And then the theory of spread spectrum communications is presented. The spread spectrum techniques used in wireless local area network nowadays mainly consist of four spread spectrum techniques： direct-sequence spread spectrum （ DSSS）, frequency-hopped spread spectrum, time-hopped spread spectrum and linear frequency modulation spread spectrum. The theory of the four spread spectrum techniques and the spread spectrum technique of anti-interference are performed in this thesis in sequence. Finally, the application of the spread spectrum techniques in wireless local area network is also investigated.
