Abstract: In the paper, we present a new class of orthogonal bipolar spreading sequences designed based on Goethals-Seidel construction with negacyclic matrices. The sequences can be designed for any length equal to 4 (mod 8), and possess good correlation properties. In particular, their aperiodic autocorrelation characteristics are very good. That can be traded off for improvement in the crosscorrelation performance using a diagonal modification method, as shown in the example. 1.
