The spectral efficiency and reliability of Multi-Input Multi-Output (MIMO) systems greatly depends on the prediction result of channel state information (CSI), such that the transmitter and/or the receiver have perfect knowledge of CSI. The employment of linear predictors used for narrow-band prediction has produced poor results in prediction of correlation coefficients of the channel in the presence of received data that has undergone non-linear distortions. Hence, one of the potential solutions to this challenge is artificial neural networks (ANN). In this paper we used fully connected recurrent neural network to predict the Rayleigh fading channel coefficients using genetic algorithm based learning, which is compared with split complex real time and fully complex real time based recurrent learning process. © 2011 Springer-Verlag.
