Summary:PROBLEM TO BE SOLVED: To reduce the effect of crosstalk in multiple inputs/multiple outputs(MIMO) DSL(Digital Subscriber Line) communication system 100 that has a transmitter processor 102 having N transmitter 125 coupled with a receiver processor 103 having L receivers 130. SOLUTION: Each receiver receives many signals including an intended signal and a number of interference signals. Each signal received by each receiver is weighted by a weight, resulting in producing a number of weighted signals. One estimate transmission signal or more where one of the weighted signals is combined is generated. The effect of each interference signal can effectively be eliminated.
