EQUALIZING DEVICE, RECEIVING DEVICE AND EQUALIZING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an equalizing device capable of improving estimation accuracy of a transmission line impulse response even under the environment where temporal fluctuation of a transmission line is quick.SOLUTION: An equalizing device 13 comprises: a quadrature transformer 31 which performs quadrature transformation on a received signal r(k) within a transformation term Tw1; a frequency axis equalizer 33; an inverse quadrature transformer 34 which performs inverse quadrature transformation on output of the frequency axis equalizer 33 and generates a main equalized signal Em; a sub quadrature transformer 41 which performs quadrature transformation on the received signal r(k) within a transformation term Tw2 (Tw2
