Özet
This work proposes a novel iterative blind receiver to jointly estimate channel parameters and transmitted data sequence on the multipath fading channel in Direct Sequence Code Division Multiple Access (DS CDMA) systems. Since time delay of the transmission channel represents nonlinear characteristic, joint estimation of these parameters and data sequence is difficult for multipath fading channels. To derive of the proposed iterative method we used completely Bayesian approach and then, Sequential Monte Carlo (SMC) technique is adapted to proposed method. © 2011 IEEE.
