Abstract联合国千年发展目标: In allusion to the demand of variable m⁃sequence in some design occasion
世界上最贵的一顿饭s, 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 generated 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塞风, 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.
