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.
