Abstract
A reception device includes an estimating unit, a rank identifying unit, a stream-number determining unit, a precoding-matrix determining unit, and a transmitting unit. The estimating unit receives a known signal transmitted from a transmission device, and estimates a channel between the transmission device and the wireless communication device and a reception signal quality. The rank identifying unit identifies a rank of a propagation path based on the estimated channel. The stream-number determining unit determines the number of data streams based on the estimated reception signal quality and the identified rank. The precoding-matrix determining unit determines a precoding matrix based on the estimated reception signal quality and the determined number of data streams. The transmitting unit transmits information relating to the determined number of data streams and the determined precoding matrix to the transmission device.
