  • Patent number: 9009207
    Abstract: Disclosed is a method for generating a sequence and an apparatus for the same which can satisfy the number M? of sequences sufficiently larger than a length N of a sequence required in a wireless communication system. When the generation of a sequence of the wireless communication system is intended, a first sequence is generated from an mth order primitive polynomial determined according to the length of a required sequence. Then, a second sequence and a third sequence are generated from the first sequence, and a remainder and a quotient is obtained by dividing a particular reference parameter by a number equal to or smaller than 2m+1. Next, a fourth sequence having a desired length N is generated by using the remainder and the quotient. Therefore, it is possible to generate sequences satisfying that the number M? of sequences is sufficiently larger than a length N of the sequence.
