This paper presents a combined higher order statistics (HOS) and second order statistics (SOS) approach to blind equalization of white as well as colored sources. Remarkable convergence speed has been achieved through an additional term in the cost function based on the energies of the source symbols. Computational complexity of the new algorithm is less than the previously proposed hybrid approach and exhibits enhanced robustness compared against low SNR. The algorithm is valid for equal energy sources and provides convergence in only one epoch (training cycle)
