Abstract
An apparatus and method for orthogonal frequency division multiplexing (OFDM) channel equalization are disclosed. The apparatus includes a compensation value setting unit setting a compensation value in the form of a diagonal matrix by use of a diagonal matrix of diagonal elements extracted from a channel matrix of an OFDM receiver, and a preset divergence suppression value, an initial estimation value calculation unit calculating an initial estimate value by use of a fast Fourier transform (FFT)-processed signal of the OFDM receiver and the compensation value, an equalization unit detecting a transmission signal to be processed by use of the compensation value, the channel matrix and the diagonal matrix, and a symbol decision unit determining a symbol for an adjacent signal of a transmission signal, which is to be processed among a plurality of signals output from the equalization unit, and providing the symbol-determined adjacent signal to the equalization unit.
