摘　　要：针对某些设计场合对可变m序列的需求,提出并验证了一种基于FPGA的m序列发生器方案。该方案采用线性反馈移位寄存器的结构,可通过外设对发生器的初始状态进行配置来改变所产生的m序列。使用Model Sim仿真软件对此设计进行了仿真,并将该m序列发生器应用于某光跳频保密通信系统中完成了实验验证。结果表明,使用该方案实现的m序列发生器结构简单、易于集成,可产生大量不同的m序列,且具有可动态配置的特点。In allusion to the demand of variable m-sequence in some design occasions,an m-sequence generator scheme based on FPGA is proposed and verified.In the scheme,the linear feedback shift register structure is adopted,and the generat?ed m-sequence can be changed by using peripherals to configure the initial state of the generator.The Modelsim simulation software is used to perform simulation for the design,and the m-sequence generator is applied to a certain optical frequency hopping secure communication system to accomplish the experimental verification.The results show that the m-sequence generator realized by this scheme has simple structure,is easy to be integrated,can produce a large number of different m-sequences,and has the characteristic of dynamic configuration.
