具备反侦察与抗截获特性的紫外光通信体制研究

从紫外光的传播特性看，它具有较强的大气散射和衰减特性，使其具有较强的绕射能力，能够有效实现非直视通信，同时能够有效控制信号的覆盖范围。因此，紫外光通信是一种具有良好反侦察、抗截获能力的通信技术体制。其中紫外光的调制解调与信道编译码技术是其关键技术。该文重点讨论多进制脉冲位置调制原理及方法，同时，也研究了各种编码方案，并提出了卷积编码作为其信道编译码的技术体制。

Research on Ultraviolet Communication Technology with the Ability of Counter-reconnaissance and Anti-interception

When propagating in the free space,the ultraviolet was attenuated and scattered strongly by the atmosphere.These characters on propagation enable the ultraviolet the ability of communication in non-line site and controlling the signal propagation arrange.So,the ultraviolet communication is a kind of communication technology with excellent ability of counter-reconnaissance and anti-interception.The modulation of ultraviolet and the FEC is the key technology of ultraviolet communication.Generally,PPM is used ...
