摘要： This equalization device and method, while preventing an expansion of circuit size, enable high-speed detection of a CIR in order to effectively achieve frequency domain equalization even when the phase of the received signal is significantly different from the phase of the known signal, and when the transmission channel has large temporal variations. A reference signal extraction unit (112) extracts both a real part component and an imaginary part component from the portion of the received signal including the known signal. A CIR detection filter unit (120) filters the known signal to generate a first processed signal and a second processed signal, detects real part filter coefficients by updating a first filter coefficient used in filtering the known signal in such a way that the first processed signal converges to the real part component, and detects imaginary part filter coefficients by filtering the known signal in such a way that the second processed signal converges to the imaginary part component. A CIR output unit (140) uses either the real part filter coefficients or the imaginary part filter coefficients to identify the channel impulse response.
