A method of estimating a communication channel in a UWB receiver according to an embodiment of the present invention includes the steps of: (a) performing a first correlation operation between a PN signal received at a UWB receiver and a local PN signal; (b) (C) a step of detecting whether a peak exists in the correlation value obtained in the second correlation operation, (d) (B) and (c) are performed by increasing the size of the correlation window in which the second correlation operation is performed; and (e) if a peak is detected, And estimating a communication channel type by comparing arrival time intervals.
