PROBLEM TO BE SOLVED: To provide a crosstalk canceller with a reduced number of redundancies. SOLUTION: A method and an apparatus are disclosed for reducing crosstalk in an unbalanced channel with a reduced number of redundancies. The crosstalk canceller is disclosed that uses a multi-dimensional finite impulse response (FIR) filter to process a received signal. Redundancies are reduced or even removed entirely by processing the signal received on each twisted pair in a vector form, using the multi-dimensional finite impulse response filter. The signal received by a transceiver on each twisted pair are represented in a vector form so that the signals received on each twisted pair, and the crosstalk effect that each signal has on one onother, can be performed collectively. The multi-dimensional crosstalk canceller processes a vector representation of the corresponding signal transmitted from the transceiver on each twisted pair. An adder sums the equalized vector representation of the signal received by the transceiver and the processed vector representation of the signal transmitted from the transceiver to generate an estimate value of the received signal on each twisted pair.
