Blind identification and equalization of downlink TCM coded MC-CDMA systems using cumulants

This paper describes a blind algorithm for TCM coded Multi Carrier Code Division Multiple Access (TCM coded MC-CDMA) systems equalization. The estimation of a time varying and selective frequency fading channel is considered. In order to identify, blindly, the impulse response of these channels, we have used Higher Order Statistics (HOS) to build our algorithm. We have selected two practical selective frequency fading channels called Broadband Radio Access Network (BRAN A and BRAN E) normalized for TCM coded MC-CDMA systems identification and equalization. For that, we have focussed on the BRAN A and BRAN E channels to develop a blind algorithm able to simulate the measured data with high accuracy.
