Reducing the Limitation on Application of Synchronous Decorrelating Detector Cdma Systems

In CDMA (Code - Division Multiple - Access) systems multi - user accessing of a channel is possible. Under the assumptions of Optimum multi - user and decorrelating detector in CDMA systems. By using signals with zero and / or identical cross correlations, a simple and expandable decorrelating detector with optimum efficiency which can be easily implemented are proposed. Constructing these signals is accomplished by encoding of the data stream by a member of orthogonal code which is then multiplied by a special signature sequences.
