A robust approach for Proakis and BRAN channel identification and equalization of MC-CDMA systems

This paper handles the problems of identification and equalization. To recognize the impulse response for frequency radio, we focus on positive kernel algorithm and we proceed to the equalization MC-CDMA systems. In this paper, we employ a broadband radio access network channels (BRAN A and BRAN E) standardized by the European Telecommunications Standards Institute (ETSI) and Proakis channels (channels A, B and C). Through theoretical analysis and the experimental simulation, it shows the appropriateness of the kernel algorithm using different SNR. To indicate the robustness of the algorithm, we have done a comparison with the RLS method. In the equalization part, we used the Zero Forcing algorithm (ZF) and Minimum Mean Square Error Algorithm (MMSE). Simulations results show that the proposed algorithm is efficient and effective for practical channels.
