Abstract :
A multi-user detector with an ability of channel estimation using a radial basis function (RBF) network is proposed in a multicarrier-code division multiple access (MC-CDMA) system. In the proposed scheme, the RBF network is connected to the frequency domain to effectively utilize the frequency diversity. Simulations were performed over the frequency selective and multipath fading channel. From these simulations, the proposed receiver is verified to be used for both the channel estimation and the multi-user receiver that permits more active users
