Channel Identification and Equalization based on Kernel Methods for Downlink Multicarrier-CDMA Systems

In this paper the authors are focused on channel identification and equalization for Multi-Carrier Code Division Multiple Access MC-CDMA system. For this, they identify the impulse response of two practical selective frequency fading channels called Broadband Radio Access Network BRAN A and BRAN B normalized by the European Telecommunications Standards Institute ETSI. To identify the channel parameters, they have the positive definite kernels to build on algorithm. The simulations show that the presented method confirms the good performance for different SNR values. In part of equalization, the authors use the Zero Forcing ZF and Minimum Mean Square Error MMSE equalizers.
