摘要
扩频通信技术具有保密、隐蔽和抗干扰等优异性能,因而具有广阔的应用前景。直接序列扩频(直扩)技术具有众所周知的许多优良特性,但常规二元直扩在灵活、有效利用频谱方面就显出了不足。探讨了一种m位移序列多进制扩频系统,分析了系统的性能和原理,为系统的仿真研究提供了数学基础。
Spread spectrum techniques have the excellent performances in the aspects of secrecy,concealment and anti-jamming,etc.Therefore,it has a wide application prospect.As known to all,direct sequence spread spectrum(DSSS) techniques also exhibit many fine properties.However,the conventional Binary-DSSS has some shortcomings in terms of the flexibility and effectiveness of spectrum utilization.A M-ary spread spectrum system of m-sequence and its displacement sequence is discussed,and its capability and theory are analyzed.A mathematical foundation for the simulation research is presented.
