Abstract: There is provided a multi-carrier transmission device capable of improving a packet error ratio in a system where transmission data is repeatedly multi-carrier-transmitted. In this device, the transmission data is subjected to error correction encoding in an error correction encoding unit (102), modulation in a modulation unit (104), and repetition in a repetition unit (106). A signal after the repetition (repetition bit) is two-dimensionally mapped in the frequency domain and the time domain according to a predetermined pattern in a mapping unit (108). The repetition bit transmission power is controlled so that the total value of the transmission power of repetition bit constituting one bit is identical to all the bits and the repetition bit of preferable reception quality has a large transmission power while the repetition bit of bad reception quality has a small transmission power.

Abstract: Interference between users in an MU-MIMO system is minimized by effective precoding, without increasing an overhead of control data. In a wireless communication system in which multiplex communication is possible between multiple UE1, UE2, and BS, a channel estimation and precoding selection unit 539 in BS estimates channels from the respective UE1, UE2 to the BS, determines a precoding matrix P from a projection matrix to make the two channel response matrices orthogonal or nearly orthogonal, and feeds back the precoding matrix P to UE2, and executes precoding on only UE2 of the two. A precoding unit 524 in the UE2 employs the precoding matrix P that has been notified to perform precoding of a data stream, and sends the precoded data stream to the BS.

Abstract: A duplicating section duplicates a bit sequence to be input, and a 16 QAM section modulates a bit sequence of a duplicating source to form a symbol, a 16 QAM section modulates the duplicated bit sequence to form a symbol, an S/P section parallel converts the symbol sequence input in series, an S/P section parallel converts the symbol sequence input in series, and an IFFT section 15 provides IFFT processing to the input symbol sequence. Since each of multiple same bits duplicated by the duplicating section is included in a different symbol, each of the multiple same bits is allocated to each of multiple subcarriers each having a different frequency by IFFT processing. As a result, a multicarrier signal including the multiple same bits each having a different frequency is generated.
