摘要： There are provided a communication device, a base station, a communication system, and a communication method that make it possible to yield a diversity effect by cooperative relay without involvement of disproportionateness in data received by an eNB even when one of parties has unsuccessfully exchanged data. After received an ACK signal from a repeater 1, a repeater 2 which has transmitted a NACK signal in procedure 7 transmits data S2 to the eNB by use of its own resource, thereby making its own resource available for the repeater 1 (the repeater 2 does not use its own resource, and the repeater 1 uses the resource of the repeater 2). In procedures 8, the repeater 1 has received the NACK signal from the repeater 2 and subsequently transmits data S1 to the eNB by use of its own resource. Subsequently, the repeater 1 which has received the MACK signal in procedure 9 determines that the resource of the repeater 2 is available and transmits data P1 to the eNB by use of the resource of the repeater 2. In procedure 10, the repeater 1 transmits previously-generated data P2 to the eNB by use of its own resource.

摘要： Provided is a wireless communication device which can improve the notification accuracy of the channel state information (CSI) without straining the feedback circuit. In this device, a channel estimator (105) uses a pilot signal input from a wireless receiver (102) to estimate the channel and obtain a plurality of path gains in each of a plurality of delay periods. Then, the channel estimator (105) outputs the plurality of path gains to a quantizer (107). The quantizer (107) quantizes the plurality of path gains in the number of notification bits corresponding to each of the plurality of delay periods based on the correspondence of the delay period and the number of notification bits input from a setting unit (106).

摘要： 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).

摘要： 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.

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).

摘要： 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.
