摘　　要：M序列是一种具有近似白噪声性质的确定序列,在工程上常用M序列代替白噪声用于系统辨识试验。针对以往M序列产生方法的不足,提出了一种基于FPGA(Field Programming Gate Array)的M序列半定制实现方案。在Quartus II编程环境下,采用硬件描述语言Verilog HDL进行设计,并使用矢量波形文件仿真测试。该设计方案具有结构简单、可靠性高、灵活性强等优点。M-sequence is a deterministic sequence and has the similar properties with white noise.It usually takes the place of white noise to be used for system identification.This paper puts forward a semi-custom implementation of M-sequence based on FPGA,and designs the program by the hardware description language Verilog HDL and gives the simulation waveforms in Quartus II programming environment.Besides,the scheme has the characters of simple structure,flexibility and reliability.
