OFDM 시스템을 위한 저면적 등화기의 구현

In OFDM system, the channel equalizer is used to correct phase distortion and amplitude attenuation, caused in the signal by the radio channel and the transceiver's nonlinear device behavior. Therefore, it is necessary to estimate the channel response in order to obtain the inverse channel frequency response. In this paper, Use pre-scaler and post compensator in order to reduce dividing rom size and fixed point error in channel estimation block. and implemented FPGA device.
