Design of m sequence generator based on protues

Pseudo-random code attains more and more people´s attention and was widely used in modern engineering. M sequence, as a pseudo-random code of the longest cycle of one of the basic sequence, has always been more research. Therefore, how to design the hardware circuit to generate m sequence is particularly important. In this paper, the nature and generated condition of m sequence were first studied, secondly, protues software was used to design and simulate the 4, 5, 13-m sequence. The simulation results show that the circuit of m sequence is correct.
