Patent ID: 7769100

Claim:
A method of canceling crosstalk signals in a receiver that receives data vectors transmitted from a transmitter and received signals including the crosstalk signals generated during the transmission of the data vectors, the method comprising: (a) a step of multi-dimensionally decomposing the received signals into a user domain and a time domain; (b) a step of calculating a transposed matrix and a diagonal matrix of a unit matrix from the received signals; (c) a step of decoding the received signals with respect to symbols in the user domain using the transposed matrix and the diagonal matrix of the unit matrix; and (d) a step of decoding the signals, which have already been decoded in the user domain with respect to symbols, in the time domain so as to calculate the data vectors from which the crosstalk signals are cancelled; wherein in the step of (d), decoding through a diagonal channel analysis of the user domain and the time domain is performed, in addition to the decoding through the user domain and the decoding through the time domain.
