基于FPGA可配置m序列发生器的设计与实现
Design and implementation of configurable m-sequence generator based on FPGA
摘要
Abstract
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 soft-ware is used to perform simulation for the design,and the m-sequence generator is applied to a certain optical frequency hop-ping 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.关键词
