频率编码水声遥控指令的抗多途对策
Some Measures fou Anti-Multipath Interference to Underwater Acoustic Remote-Controlled Command by Frequency Code
Abstract
浅海信道中，多途干扰是水声遥控指令可靠检测的首要障碍，本文探讨频率编码遥控指令的抗多途对策，即通过阻塞多途来削落多途干扰。 Multipath interference hinders chiefly from detecting reliably an underwater acoustic reomte-controlled command in shallow-water channels.Some measures of anti-multipath interference are discussed on a remote-controlled command by frequency code in this paper,that is,multipath carriers are blocked off in the receiving circuits to remove multipath interference.
