    摘要: In using frequency selective precoding to a multicarrier signal, notification is provided with control information. A radio transmitter, divides a frequency signal into a plurality of clusters, arranges each of the divided clusters on a frequency domain and multiplies each of the clusters by a precoding matrix, limits the number of precoding matrices to be selected based on the relationship between a precoding matrix to be multiplied to any of the clusters and a precoding matrix to be multiplied to any of the other clusters. The number of precoding matrices to be selected is limited based on the relationship between a precoding matrix to be multiplied to any one of the clusters and a precoding matrix to be multiplied to another cluster neighboring thereto. The number of precoding matrices to be selected is limited based on frequency correlation between any one of the clusters and another cluster neighboring thereto.
