We investigate the scenario of an upstream coordinated DSL transmission inpresence of spatial-correlated noise. Joint signal processing helps mitigate this noise and reduceinternal interference effects between coordinated users. We propose to couple noise whitening witha mean-squared error iterative receiver in order to approach the matched filter bound of the DSLcoordinated system. The convergence of the iterative scheme in this scenario is predicted usingEXIT charts under realistic transmission conditions
