WIRELESS COMMUNICATION BASE STATION DEVICE, WIRELESS COMMUNICATION MOBILE STATION DEVICE, AND PROPAGATION PATH ESTIMATION METHOD

摘要

A wireless communication base station device, whereby precision of propagation path estimation is improved by making possible determination of the contiguity of precoding strings contiguous in frequency regions. In this device, a pre-coding string contiguity determining portion (120) determines whether or not a plurality of pre-coding strings (?) which are input from a pre-coding string calculating portion (119) are contiguous in a frequency region. The pre-coding string contiguity determining portion (120) outputs smoothing possibility data, which indicate determination results, to a control data generating portion (104). The control data generating portion (104) generates control data indicating smoothing possibility data which is input from the pre-coding string contiguity determining portion (120).
