Selection of Direct Spread Spectrum Sequence in Point to Multipoint Wireless Local Area Network
Zhang Yong-jie · Radio Engineering of China · 2009
The selection and constitution of spread spectrum sequence is one of the key technologies in design of spread spectrum communication system.The ability of anti-jamming,anti-fading,anti-interception,secrecy and synchronization of the communication system is closely correlative with the used spread spectrum sequence.The better correlation and randomicity of spread spectrum sequence play crucial role to improve the performance of system.The direct sequence spread spectrum is used in point to multipoint WLAN.In order to meet the practical need,five kinds of direct sequences which have better performance are found through analyzing and studying m spectrum,M spectrum,gold spectrum,kasami spectrum.
