A blind adaptive decorrelating detector for CDMA systems
The decorrelating detector is known to elimi nate the multi access interference given that the signature sequences of the users are linearly independent at the cost of enhancing the Gaussian receiver noise In this paper we present and study the convergence of a blind adaptive decorrelating detector which is based on the observation of the available statistics The algorithm is iterative and dis ...

The decorrelating detector is known to eliminate multiaccess interference when the signature sequences of the users are linearly independent, at the cost of enhancing the Gaussian receiver noise. In this paper, we present a blind adaptive decorrelating detector which is based on the observation of readily available statistics. The algorithm recursively updates the filter coefficients of a desir...
متن کاملAdaptive decorrelating detectors for CDMA systems
Multi-user detection allows for the efficient use of bandwidth in Code-Division Multiple-Access (CDMA) channels through mitigation of near-far effects and multiple-access noise limitations. Due to its inherent noise and multipath immunity, CDMA multi-access is being considered as a platform for personal communication systems (PCS). As CDMA based digital communication networks proliferate, the n...
متن کاملAnalysis of an adaptive decorrelating detector for synchronous CDMA channels
Multiuser detection allows for the eecient use of bandwidth in Code Division Multiple Access (CDMA) channels through mitigation of near-far eeects and multiple-access noise limitations. The decorrelating detector, developed by Lupas, is a linear multiuser detector that is asymptotically optimal in terms of near far resistance when certain communication parameters are completely known to the det...
متن کاملReducing 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 sign...
