摘　　要：本文研究了由线性反馈移位寄存器(Linear Feedback Shift Registers,LFSR)生成m序列的原理,并对LFSR电路结构作了改进,利用基于现代DSP技术的DSP Builder软件,设计了一种周期、相位可调的m序列发生器。经调试与仿真,结果表明该方法硬件结构简单、开发周期短,为系统设计或测试带来很大的便利。In this paper, the theory of the m sequence produced by linear feedback shift registers（LFSR） is studied, by modifying the LFSR circuit structure, a programmable m sequence generator is realized with DSP Builder, a software based on modern DSP techniques. The design is debugged and simulated, and the results indicated that the proposed method with the merit of short development cycle, simple in hardware structure and easy in controlling the period and phase of the m sequence. In many projects, it is also a great advantage for designing and debugging system.
