| 摘要: |
| 介绍了对移位寄存器的每一位状态进行加权求和产生m序列的方法.该方法可以在移位寄存器初相不变的情况下仅改变加权系数就能得到不同初相的m序列.文中进一步证明了非零加权系数向量与n级移位寄存器产生的m序列初相具有一一对应关系.该方法简化了多路m序列的生成,实现非常简单,可用于改进扩频通信系统中伪码的捕获电路. |

| Abstract: |
| A method using weighting coefficients to generate m sequences is presented, which calculates the weighted sum of every bit of the shift - registers and the result is the same m sequence except for another phase. It is proved that every non - zero weighting coefficient vector maps one - to - one a phase of m sequence. It is very simple to implement the method, and it can be used to improve the circuit for pseudocode acquisition in spread spectrum communication systems. |
