Abstract: Disclosed is a wireless transmitter that can prevent deterioration of the error rate characteristic without reducing the data rate during mobile communications also utilizing THP for FDE. In the device, an equivalent channel matrix computation unit (118) computes weights to be used for FDE of a transmission block and an equivalent channel matrix indicating equivalent channels that are generated from channel impulse responses, and a decomposition unit (119) obtains a lower triangular matrix (L), that consists of a diagonal element that includes a high channel quality at the front of the transmitting block and a low channel quality at the rear, so as to indicate the channel quality of the transmission block, and an element indicating interference with the transmission block, and a unitary matrix (Q) by means of LQ decomposition of the equivalent channel matrix. A computation unit (120) uses the lower triangular matrix (L) and the average channel quality to compute a matrix (B) that minimizes the mean square error of all symbols between the transmission block before precoding and a block received by a wireless receiver. A preceding unit (103) performs THP of the transmission block using the matrix (B).

Abstract: Provided is a wireless communication apparatus by which reduction of a diversity gain can be suppressed at minimum in the case of employing a repetition technology in multicarrier communication. In the wireless communication apparatus (100), repetition sections (102-1 to 102-n) repeat each data symbol inputted from modulating sections (101-1 to 101-n) to create a plurality of identical data symbols. An allocating section (103) outputs each data symbol to a multiplexing section (105) by allocating the data symbol to a plurality of subcarriers constituting an OFDM symbol. At this time, the allocating section (103) allocates at least one of the repeated identical symbols to a subcarrier different from a subcarrier to which the symbol is allocated in an adjacent sector.

Abstract: Disclosed is a radio communication device capable of improving the usage efficiency of resources in multi-stage relay to reduce the amount of delay of a relay signal and improving the reception quality of signals by a relay station or a base station. A transmission determining unit 16 determines whether to transmit the relay signal and whether to transmit ACK/NACK on the basis of whether there is an error in the relay signal, and on the basis of ACK/NACK received from a one-hop-downstream radio communication device. An MCS determining unit 17 provided in the transmission determining unit 16 determines an MCS for the relay signal. A transmission instruction generated by the transmission determining unit 16 is output to a buffer 11 and an ACK/NACK generating unit 19. The determined MCS is output to an error correction coding unit 12 and a modulation unit 13. The ACK/NACK generating unit 19 generates ACK when there is no error in the relay signal, and generates NACK when there is an error in the relay signal.
