Abstract: Provided is a method and system for estimating a channel in a wireless communication system. An interference coefficient is calculated based on a known structure of a pilot, and a channel value in a frequency domain is estimated. A channel value in a time domain is obtained by transforming the channel value in the frequency domain and the channel delay values are subtracted from the channel value in the time domain, thereby cancelling interference.

Abstract: Disclosed is an automatic gain control device in an orthogonal frequency division multiplexing system. A variable gain amplifier controls a gain of an input signal; an energy calculator calculates an energy of the input signal; a truncator accumulates the calculated energies, finds an average thereof, and generates a DC offset of the input signal; a subtracter subtracts a predefined reference value from the DC offset, and outputs a signal; and an RC filter feeds the value output by the subtracter back to the variable gain amplifier so that the value output by the subtracter may be used for an automatic gain control. The predefined reference value given to be 4.Ov is a reference power generated based on a saturation to RMS ratio for minimizing the bit error rate of the orthogonal frequency division multiplexing system.
