摘要
研究了伪随机序列的随机特征,推导出M序列具备伪随机序列的特征,给出M序列的反馈逻辑函数,设计了M序列发生器;分析了测试电路产生的n阶伪随机序列的波形图。通过对测试结果的分析、比较发现,关于反馈移位寄存器的阶数与序列长度关系、码元的游程(该序列的伪随机性)等方面的分析是正确的,验证了该设计的可行性。
The random characteristics of pseudo-random sequence has been investigated,and the characteristics of \%M\% sequence has been educed, the feedback logic function of \%M\% sequence has been deduced, the \%M\% Sequence occur has been designed, the waveform of pseudo-random sequence was tested,the testing result has been analyzed and compared the relationship about the steps of feedback shift register, sequence length and travel of code (pseudo-random characteristic of the sequence) are correct. the feasibility of design was validated.
