摘要： Provided is a base station capable of performing cell search of all mobile stations having different communicable frequency band widths in a scalable band width communication system to which a multi-carrier communication method such as the OFDM method is applied. The base station includes: a modulation unit (102) for modulating SCH data after being encoded; a sub carrier setting unit (105) for setting one of the sub carriers to a sub carrier (SCH sub carrier) constituting the OFDM symbol for SCH data transmission; and an IFFT unit (106) for mapping the SCH data to the sub carrier set by the sub carrier setting unit (105) among the sub carriers and performing IFFT to generate an OFDM symbol. The sub carrier setting unit (105) sets one of the sub carriers which has a frequency of a common multiple between the sub carrier interval and the cell search interval as an SCH sub carrier.

A GI adding part adds a short GI or a long GI to the head of each of a plurality of data parts. In a case of adding the long GI, the GI adding part copies the symbols of a portion of a second data part, which immediately follows a first data part, including the rear of the second data part, and then adds the copied symbols to the head of the first data part, thereby providing a second GI. Moreover, the GI adding part copies the symbols to a portion of the first data part including the rear thereof, and then adds the copied symbols to the head of the second GI, thereby providing the first GI.

摘要： A communication relay apparatus wherein the error rate characteristic of a relay destination is improved to raise the throughput, while reducing the given interference power to prevent the reduction of the throughput of the whole communication system. In the apparatus, a signal addressed to a base station is received (ST1010), and a decoding process and other processes are performed (ST1020). A bit error determination is performed (ST1030), and if there is no bit error, a reproduction/relay process (ST1050) is performed. If there is any bit error, a threshold-based determination of reception quality is performed for each of subcarriers (ST1120-1130). If the reception quality is greater than a threshold value, the corresponding subcarrier is outputted (ST1140); otherwise, the corresponding subcarrier is not relayed (ST1150). A signal, which has been subjected to either process, is transmitted (ST1060).

摘要： Provided are a radio reception device, a radio transmission device, and a feedback method which can uniformly guarantee the feedback accuracy of an average CQI even when the transmission band width is different. A channel estimation unit (103) uses a pilot signal to obtain SINR for each RB. A feedback information generation unit (107) converts SINR of each RB into a corresponding CQI. Moreover, as the transmission band width increases, the number X of the quantization bits is decreased when quantizing the average CQI, thereby generating feedback information. A radio transmission unit (108) transmits feedback information from an antenna (101).

摘要： Provided are a radio transmission device and a radio transmission method, which prevent the deterioration of a preamble detecting performance while reducing the collision probability of a RACH. In this radio transmission device, a Signature table storage unit (103) divides the magnitudes of transmission loss levels into individual levels corresponding to the distances from a base station, to cause CAZAC series and circulation shift quantities to correspond to each other at the individual levels, and is provided with a table containing a plurality of Signatures created from the CAZAC series and the circulation shift quantities caused to correspond to each other. A Signature selecting unit (104) selects one of the corresponding Signatures at random from the Signature table storage unit (103), on the basis of the magnitude of the transmission loss level outputted from a transmission loss level deciding unit (102). A RACH signal generating unit (105) generates the RACH signal with the Signature selected.

摘要： A wireless receiving apparatus capable of efficiently removing interference signals in a multicarrier communication. In a mobile station incorporating this wireless receiving apparatus, a selecting part selects a plurality of the same symbols in accordance with a mapping pattern established at the time of generating OFDM symbols in a base station. A correlation value calculating part determines correlation values between the subcarriers of the same symbols to generate an R-matrix, and further determines an inverse matrix of the R-matrix. An MMSE processing part performs an MMSE processing to determine a weight from both a P-vector received from a channel estimating part and the inverse matrix of the R-matrix received from the correlation value calculating part. Multipliers multiply each of the symbols selected by the selecting part by the weight determined by the MMSE processing part. A combining part combines the symbols as multiplied by the weight.

摘要： A radio receiver apparatus that can effectively utilize GI to improve the reception quality. In this apparatus, a data extracting part (104) extracts a data portion of a direct wave from a signal subjected to a radio reception process by a received RF part (102). A GI extracting part (107) extracts, from the signal subjected to the radio reception process by the received RF part (102), GI having a length determined by an extracted GI length deciding part (106). The extracted GI is adjusted by a data position adjusting part (108) such that its rear end coincides with the read end of the extracted data portion. A combining part (109) combines the extracted data portion with the GI the data position of which has been adjusted. The combined signal is then supplied to a frequency axis equalizing part (110), which equalizes the signal distortions of the combined signal on the frequency axis.
