Abstract
A mobile receiver performs oblique interpolation in such a direction that a symbol number increases by one and a carrier number decreases by three with respect to a position of each Scattered Pilot Signal to interpolate a first signal whose channel characteristics have not been obtained. The mobile receiver then performs, in a frequency axis direction, frequency axis interpolation to interpolate channel characteristics of a second signal whose channel characteristics have not been obtained, using the estimated channel characteristics and the interpolated channel characteristics.
