首先分析得出由于两者的反馈输出关系不同,m序列发生器SSRG和MSRG在同种本原多项式条件下产生不同序列,且本原多项式下构架的SSRG和与其对偶多项式下构架的MSRG可使两者具有相同的反馈输出关系.由此,利用本原多形式与其对偶多形式的镜... 首先分析得出由于两者的反馈输出关系不同,m序列发生器SSRG和MSRG在同种本原多项式条件下产生不同序列,且本原多项式下构架的SSRG和与其对偶多项式下构架的MSRG可使两者具有相同的反馈输出关系.由此,利用本原多形式与其对偶多形式的镜像对称特性得出一种简单的寻找生成同种序列的SSRG和MSRG的方法,及同种本原多项式下生成不同SSRG和MSRG伪码序列的方法. 展开更多

Hardware implementation of Linear Feedback Shift Register (LFSR) plays a great and very important role in communication systems, and in many security devices. In this paper, a design of LFSR with offset mask has been presented, for Direct Sequence Code Division Multiple Access (DS-CDMA) applications. Integrated electronic components have been used. An accessible model facilitating the synthesis on Printed Circuit Boards (PCB) and implementation on Field Programmable Gate Array (FPGA) is offered. In addition, a temporal and spectral analysis of the circuit is performed in order to validate the design. This latter facilitates the generation of pseudo-random codes based on LFSR and their integration into electronic systems. 展开更多
