Abstract
Recently a new family of complex-valued spreading sequences was propos ed for code-division multiple-access (CDMA) systems [1], [2], which of fer the system designer the choice of a wide range of correlation prop erties, This letter identifies a subfamily of spreading sequences for use in CDMA systems in which the sequence elements in any set are orth ogonal, The subfamily also offers a very wide range of values for both aperiodic auto-correlation (AC) and aperiodic cross-correlation (CC) functions with the added property of having orthogonal elements.
