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