Research on cyclic non-repeated codes based on FPGA

对激光信号进行有效的编码,可以减弱敌方干扰的效果,传递大量的战场信息,从而使军演更加贴近实际战场。文中详细地介绍了循环不重复码的基本编码原理。使用FPGA技术实现了发射编码激光脉冲的功能和接收编码激光脉冲的功能,通过modelsim进行了功能仿真,仿真结果表明发射模块和接收模块能成功发射和接收编码激光脉冲,从而实现战场上信息的传递。使用FPGA技术提升了战场信息传输的实时性,同时循环不重复码具有更好的抗干扰能力。

Effective encoding of laser signals can reduce the effect of enemy interference and transmit a large amount of battlefield information,thereby making military exercises closer to the actual battlefield.The basic coding principle of cyclic non-repeated codes is introduced in detail in the article.Use FPGA technology to realize the function of transmitting coded laser pulse and receiving coded laser pulse function,the function simulation is carried out through,and the simulation results show that the transmitting module and the receiving module can successfully transmission of information on the battlefield.The use of FPGA technology improves the real time performance of battlefield information transmission,and the cyclic non-repeated code has better anti-interference ability.
