Abstract

This paper presents a blind decorrelating detector for asynchronous multicarrier CDMA systems with Rayleigh fading channel. The detector is derived by making use of the cross correlation matrix between the consecutively received signals. The main attraction of the detection algorithm is its simplicity since the detector can be implemented blindly without any channel estimation except for the synchronization of the desired user. Simulation results are provided to demonstrate the significant gains in performance and simplicity achieved by the proposed detector.
