英文摘要：

For any prime number p and even n= 2k , a family of p-ary sequences S（r） containing p^n -sequences of period p^n- 1 was proposed, where pP^k≠2（rood3）,r and r relatively prime to p^n --1. Based on d-form function, it is proved that the nontriviaI crosscorrelation values are -1± pk, - 1, -1 ＋ 2 · p^k , and the correlation distribution is completely determined. The low bound of linear spans of the proposed family is proved to be large by generalized key methods. This family of sequences is suitable for CDMA systems and cryptography.
