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).
