| Abstract: | Based on sequences with two-level correlation and optimum quadriphase sequences, a new family of quadriphase sequences with parameter (22J-1,2J+1,2J+1) is proposed for a class of positive integers J. The new sequences family is optimal with respect to Welch’s lower bound on the maximum nontrival correlation value and it is suitable for CDMA. |
