Abstract
A load can reduce the set transport format of and can inhibit the wireless communication device increases the size of the device. In the device the spatial multiplexing fitness detection unit (108) each of which is divided in multicarrier transmission Ns sub-carrier signal obtained by the communication band dividing the frequency band (DB-1 to DB-Nd) belonging to the plurality of sub-carrier signals and detect the spatial multiplexing transmission fitness and outputs the detection result (# 1 % Nd). transmission format setting unit (110) based on spatial multiplexing fitness detection unit (108) to obtain the detection result (# 1 % Nd) setting the transmission format for wireless transmission.
A radio communication apparatus wherein the load during setting a transmission format is a reduced one and the increase in the apparatus scale is suppressed. In the apparatus a spatial multiplexing goodness-of-fit determining part (108) determines the spatial multiplexing transmission goodness-of-fit for each of divided bands (DB-1 to DB-Nd) that is obtained by dividing the communication band to which a number Ns of subcarrier signals in a multicarrier transmission belong and that is used to transmit a plurality of subcarrier signals belonging thereto. Then the spatial multiplexing goodness-of-fit determining part (108) outputs the determination results (#1 to #Nd). A transmission format setting part (110) sets a transmission format used for a radio transmission based on the determination results (#1 to #Nd) from the spatial multiplexing goodness-of-fit determining part (108).
