扩频通信技术是一种信息传输方式，其信号所占有的频带宽度远大于所传信息必需的最小带宽；频带的扩展是通过一个独立的码序列来完成，用编码及调制的方法来实现的，与所传信息数据无关；在接收端则用同样的码进行相关同步接收、解扩及恢复所传信息数据。-Spread spectrum communication technology is a way of information transmission, the band width of the signals than preaching information required minimum bandwidth Frequency band extension is done through an independent code sequence, use the method of coding and modulation, has nothing to do with the preaching information data At the receiving end with the same code for related syncing preaching information data, the solution to the recovery.
