Abstract

The performance of direct-sequence code-division multiple-access (DS-CDMA) systems crucially depends on the correlation properties of the spreading-sequences assigned to the users. Widely accepted performance measures for the correlation properties are the aperiodic mean-square correlation parameters. We investigate the aperiodic mean-square correlation parameters of various sequence families and discuss their technical meaning
