摘要： Provided is a radio communication device capable of preventing lowering of the frequency diversity effect when using the CDD (Cyclic Delay Diversity) in combination with the frequency diversity technique in a multi-carrier communication. In the radio communication device (100), a repetition unit (103) repeats each symbol to generate the same symbol, an S/P unit (104) converts a symbol string inputted in series from the repetition unit (103) into a parallel string, and an arrangement unit (105) arranges a plurality of symbols inputted in parallel to any of a plurality of sub-carriers constituting the OFDM symbol. Here, the arrangement unit (105) correlates a plurality of the same symbols generated by repetition to a cyclic delay in the CDD and arranges them to any of the sub-carries constituting each of the OFDM symbols at a sub-carrier interval based on the number of antennas and the delay amount of the CDD transmission.

摘要： In ARQ where a plurality of mobile stations share and use a single channel for response signals (ACK/NACK signals), a wireless communication base station apparatus can prevent failure of the ARQ control. In this apparatus, a CRC part (114) performs an error detection using CRC for an uplink data, and generates, as a response signal, an ACK signal in a case of CRC=OK or a NACK signal in a case of CRC=NG. A retransmittal determining part (115) determines whether the response signal is for an initially transmitted data or for a retransmitted data. A constellation control part (116) controls, in accordance with a determination result of the retransmittal determining part (115), a constellation pattern to be used in a modulation in a modulating part (105). The modulating part (105) modulates the response signal for the retransmitted data in accordance with the constellation pattern controlled by the constellation control part (116), that is, a constellation pattern obtained by reversing the constellation pattern of the response signal for the initially transmitted data.

摘要： A radio communication apparatus is provided that enables degradation of error rate performance due to puncturing to be minimized when an LDPC code is used as an error correcting code. In this apparatus, a padding bit insertion section 101 inserts padding bits in a transmission bit sequence based on a parity check matrix, and outputs the generated bit sequence to an LDPC encoding section 102. Using the parity check matrix, LDPC encoding section 102 performs LDPC encoding on the bit sequence input from padding bit insertion section 101, and obtains an LDPC codeword composed of systematic bits and parity bits. Then a puncturing section 103 eliminates padding bits from the LDPC codeword input from. LDPC encoding section 102, and also punctures parity bits in the LDPC codeword in order starting from a parity bit corresponding to a variable node for which the total number of connections to padding bits via check nodes is larger.

摘要： Disclosed are a wireless communication base station device and a division number determination method that improves the frequency diversity effect while maintaining channel estimation accuracy regardless of the number of divisions in the frequency domain of a transmission signal from a wireless communication terminal device. A determination unit (117) determines the number of divisions in the frequency domain of a transmission signal from a wireless communication terminal device. Here, the determination unit (117) increases the number of divisions in the frequency domain of the transmission signal from the wireless communication terminal device as the number of pilot blocks included in the transmission signal increases. In addition, a scheduling unit (118) schedules allocation to the frequency resources of the divided transmission signal according to the number of divisions determined by the determination unit (117).
