Abstract
A method and apparatus for estimating a channel efficiently though pilot subcarrier signal transformation and noise reduction in the mobile communication system are provided. The apparatus includes a time domain transformer for transforming received pilot subcarrier signals to time domain signals, a noise reducer for reducing noises of the time domain signals, a frequency domain transformer for transforming the noise-reduced time domain signals to frequency domain signals, and a final channel estimator for estimating channel values of data subcarriers received using the frequency domain signals. The channel estimation method and apparatus of improves performance with the reduction of computational complexity.
