Abstract
A base station transmits a control channel transmitted before information channels upon performing differential coding between control channels of adjacent frequencies. A terminal apparatus performs transmission path estimation on the basis of a pilot while decoding the control channel having undergone the differential coding. The information channels are decoded on the basis of information obtained by decoding the control channel and a transmission path estimation result on the pilot.
