摘要： Provided is a radio communication device which can reduce ISI caused by destruction of an orthogonal DFT matrix even when an SC-FDMA signal is divided into a plurality of clusters and the clusters are respectively mapped to discontinuous frequency bands. The radio communication device includes a DFT unit (110), a division unit (111), and a mapping unit (112). The DFT unit (110) uses the DFT matrix to execute a DFT process on a symbol sequence in a time region to generate a signal (SC-FDMA signal) of the frequency region. The division unit (111) generates a plurality of clusters by dividing the SC-FDMA signal with a partially orthogonal bandwidth corresponding to the vector length of some of the column vectors constituting the DFT matrix used in the DFT unit (110) and orthogonally intersecting at least partially. The mapping unit (112) maps the clusters to discontinuous frequency bands.

摘要： 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).
