Özet
In this work, based on a sequential Monte Carlo Method (particle filtering) a new Bayesian based iterative receiver is presented for jointly estimation of channel parameters and multiuser detection (MUD) of transmitted data sequence over the multipath fading channel in Direct Sequence Code Division Multiple Access (DS CDMA) systems. The parameter estimation of the transmission channel together with transmitted data sequence is difficult in the multipath environment since time delay of the transmission channel represents nonlinear characteristic. Therefore, we used completely Bayesian approach to overcome nonlinear characteristic of the channel with respect to time delay. © 2011 Chamber of Turkish Electric.
