<p>PURPOSE: An orthogonal frequency division multiplexing receiver is provided to improve signal/noise ratio by compensating sampling offset compensation. CONSTITUTION: In an orthogonal frequency division multiplexing receiver, an offset compensation unit(120) receives a digital signal outputted from a sampling offset and a-D converter. The offset compensation unit converts the digital signal based on the sampling offset into a baseband signal. An FFT block(130) converts a signal outputted through FFT from the offset compensation unit into the signal in a frequency domain. A control unit(140) generates a control signals of an OFDM symbol information and a multiple based on the FFT result. A channel impulse response estimation block(150) periodically generates impulse response information of the receive channel based on the FFT result.</p> |
