Abstract: A method of operating a repeater comprises selecting some of adaptive filter coefficients among a plurality of adaptive filter coefficients of an adaptive filter used for interference cancellation, based on the size of a coefficient, generating a predicted interference signal using the selected adaptive filter coefficients and generating an interference-canceled communication signal from a received signal using the generated predicted interference signal.

Abstract: A holographic data reproduction apparatus is provided. The holographic data reproduction apparatus includes: a charged-coupled device (CCD) that photographs diffracted-light from a recording medium irradiated with reference light, wherein the diffracted-light corresponds to a data page, an operation unit that calculates an optimal threshold value by applying a fitness function (Fit) to a genetic algorithm for detecting a number of error bits of the data page corresponding to the diffracted-light, a control unit that determines an output value of each pixel of the data page based on the optimal threshold value, and a decoding unit that decodes and outputs reproduction data according to the output value of the each pixel. Accordingly, it is possible to minimize a bit error rate (BER) and accurately reproduce holographic data.
