Abstract:
Pseudorandom sequences with good properties are important for many practical applications,such as code division multiple access(CDMA)communication systems and cryptography.The sequences with good autocorrelation are needed in some well-known applications.In CDMA systems,several users share the same bandwidth,and each user is assigned a distinct spreading sequence.In order to distinguish each other and minimize interference due to competing and simultaneous traffic across the same channel,the employed sequences are required to have low correlation.Let p,q be distinct primes with gcd(p-1,q-1)=2.In this paper,a class of Whiteman generalized cyclotomic binary sequence with period N=pq is constructed,and the autocorrelation value of the sequence is given.
