  • System and method for large dimension equalization using small dimension equalizers
    Patent number: 9787356
    Abstract: An equalizer includes an equalizer circuit including a signal input to receive a first frequency-domain signal, another signal input to receive a second frequency-domain signal, and an equalized signal output to provide a first equalized signal based upon the first and second frequency-domain signals. Another equalizer circuit includes a signal input to receive a third frequency-domain signal, another signal input to receive a fourth frequency-domain signal, and an equalized signal output to provide a second equalized signal based upon the third and fourth frequency-domain signals. A third equalizer circuit includes a signal input coupled to the equalized signal output of the first equalizer circuit to receive the first equalized signal, another signal input coupled to the equalized signal output of the second equalizer circuit to receive the second equalized signal, and an equalized signal output to provide a third equalized signal based upon the first and second equalized signals.
