Second order statistics based blind channel equalization with correlated sources

In this paper the blind equalization method of Tong, Xu and Kailath, which was derived under the assumption of a white transmitted sequence, is generalized in order to include correlated sources. The resulting algorithm can be applied to arbitrarily colored sources, assuming that the source second-order statistics are known. Because it makes explicit use of this information, the new algorithm is expected to outperform subspace based methods which neither require nor exploit such knowledge. This is verified via simulations
