Analytical Method for Blind Binary Signal Separation

The blind separation of multiple co-channel binary digital signals using an antenna array involves finding a factorization of a data matrix into , where all entries of are 1o r 1. It is shown that this problem can be solved exactly and noniteratively, via a certain generalized eigenvalue decomposition. As indicated by simulations, the algorithm is robust in the presence of noise. An interesting implication is that certain cluster segmentation problems can be solved using eigenvalue techniques.
