Abstract:
1. A method of canceling communication system noise interference, the method comprising the steps of: (a) receiving T blocks of data, Y(:, t), t=1, . . . , T, comprising T blocks of data, X(:,t), t=1, . . . , T, transmitted over predetermined subchannels; (b) determining a set of the predetermined subchannels, k(n), to generate coefficients for a multichannel frequency domain equalizer (FEQ) of a subchannel n of the predetermined subchannels; (c) generating multichannel FEQ coefficients, g(n), for the subchannel n of the predetermined subchannels used to transmit the received T blocks of data; and (d) performing multichannel frequency domain equalization for the subchannel n using the generated multichannel FEQ coefficients; wherein the step of determining the set of the predetermined subchannels, k(n), for the subchannel n includes selecting subchannel n; wherein the step of determining the set of the predetermined subchannels, k(n), for the subchannel n further includes selecting neighboring subchannels to the subchannel n.
