Design of the all status pseudo-random sequences generator

Two major problems of designing pseudo-random sequence generator are how to choose the feedback function and how to generate the complete feedback sequence. The primitive polynomial of 3-12 pseudo-random sequence generator is obtained after the deduction. The better nonlinear feedback function of all states pseudo-random sequence generator can be picked out according to the characteristic of pseudorandom sequence signal, then using all states of shifting counter through modifying the linear shift register feedback network to realize the all states pseudo-random sequence signal. Meanwhile the 12 bit all states pseudo-random sequence generator is realised by using FPGA and the sequence is emulated in the software of MAX-PLUS II.
