Abstract :
M-sequence is the earliest pseudo random sequence that was used widely, it has good randomness and balance. But it has a disadvantage in the amount of address code. This paper puts forward a method which use at last two m-sequence to output in the order. The new sequence has good correlation function and it has a big promotion in the amount of address and the variety of the period that make it has extensive applications in CDMA and communication encryption.
