- 设pn序列长度为Lc,为输入信号的Lc倍,输入带宽为f,则经过扩频后,信道中传输信号的带宽为Lc*f,.躁声也衰减为原来的1/Lc。在解调端用相同的pn序列进行解调。这样的好处是频带扩宽了,有利于对传送信号的保密,只有知道调制端的pn序列,才能正确地解调出信号;另外,由于躁声的衰减,在很大程度上降低了误码率

- 建立水声信道的射线模型在工程应用上有重要的意义。射线声学是把声波的 传播看作是一束无数条垂直于等相位面的射线的传播,每一条射线与等相位面相 垂直,称为声线。声线途经的距离代表波传播的路程,声线经历的时问为波传播 的时间。声线束所携带的能量即为波传播的声能量。与几何光学相似,射线声学 的描述方法给人直观的感觉,在一定的条件下,射线声学的数学运算也比较简捷, 由射线理论给出的声线图可以给声场以直观、形象的理解。 本模型可以准确的衡量声波在海洋中传播路径(Establishing ray
