Claim One:
1. The method of obtaining a plurality of received signals in a MIMO system with K transmission elements and N reception elements, wherein N≧K (N>2, K>1), said method comprising steps of: A. Obtaining channel coefficients matrix. B. Obtaining a plurality of K transmission channels. C. Decomposing said channel coefficients matrix using a WB factorization, wherein the bandwidth of the decomposed matrix is b. D. Running an iterative process for obtaining K received signals while applying the MLE algorithm on all sub sequence combinations of K transmitted signals according to the transmitted signal vector propagated through the decomposed channel coefficients matrix and wherein at each iteration stage, i (i={0.. . K}), a likelihood value is calculated an updated in accordance with a single reduced received signal of index K−i calculated from combination of b transmitted signals of indices i to i+b−1 and the subsequence of reduced received signals of indices K−i+1 to K calculated from the combination of transmitted signals of matching indices.
