Abstract :
An extended complex radial basis function (CRBF) network is proposed for the equalisation of a 4-QAM digital communication channel in the presence of additive white Gaussian noise and co-channel interference. The proposed model has complex valued regression weights in the output layer, and the hidden unit is defined by a real valued Gaussian formula with Mahalanobis distance. It is shown by simulation that the proposed structure gives reduced computational complexity without leading to a degradation in performance
