Blind Identification Channel Using Higher Order Cumulants with Application to Equalization for MC−CDMA System

In this paper we propose an algorithm based on
higher order cumulants, for blind impulse response identification
of frequency radio channels and downlink (MC−CDMA) system
Equalization. In order to test its efficiency, we have compared with
another algorithm proposed in the literature, for that we considered
on theoretical channel as the Proakis’s ‘B’ channel and practical
frequency selective fading channel, called Broadband Radio Access
Network (BRAN C), normalized for (MC−CDMA) systems, excited
by non-Gaussian sequences. In the part of (MC−CDMA), we use the
Minimum Mean Square Error (MMSE) equalizer after the channel
identification to correct the channel’s distortion. The simulation
results, in noisy environment and for different signal to noise ratio
(SNR), are presented to illustrate the accuracy of the proposed
algorithm.
