摘要
针对伪随机序列信号产生的疑难问题,提出了通过设计非线性移位计数器的反馈网络函数,并根据伪随机序列三个性质,即平衡特性、游程特性、相关特性,遴选出能够实现性能优良的多位全状态伪随机序列发生器的非线性网络.给出了应用VHDL语言实现8位全状态伪随机序列的程序及应用MAXPLUSⅡ软件对该序列进行仿真的结果,并通过现场可编程阵列FPGA实现全状态伪随机序列发生器.
Aiming at the problems brougth about by pseudo-random sequence, the paper puts forward the method to choose the nonlinear feedback network, which can make full use of muliti-bit all-state pseudorandom sequence generator, by designing the feedback network function of nonlinear shift counter and using the three characteristics of pseudo-random sequence： the balanced characteristic, run-course characteristic, correlation characteristic. Also, the authors gives the program which is to realize 8-bit allstate pseudo-random sequence by using VHDL language and simulating by using maxplus Ⅱ. Lastly, FPGA is employed for all-state pseudo-random sequence generator.
