Abstract: A pilot reception power measuring section 104 measures reception power of a pilot symbol and a data section reception power prediction section 106 predicts reception power of data symbols based on the reception power of the pilot symbol. A power comparison section 107 calculates a difference between this predicted value and the actual reception power of the data symbol, and when the difference is large, a collision position detection section 108 regards the data symbol at the hopping position as colliding with data symbols in other cells. Then, an error correcting decoding section 103 carries out error correcting processing by reducing likelihood of the data symbols detected to be involved in the collision and can thereby improve the error rate characteristic of decoded data.

Abstract: A wireless transmitting apparatus capable of improving the reception characteristic at a data stream receiving end. In this apparatus, I/Q separating parts (110, 112) each separate first data modulated symbols included in any of a plurality of data streams, which are to be multiplexed, into first in-phase components and first orthogonal components, while separating second data modulated symbols included in the other ones of the plurality of data streams into second in-phase components and second orthogonal components. An I/Q converting part (114) converts the first in-phase components to third orthogonal components, while converting the second orthogonal components to fourth in-phase components. A multi-code multiplexing part multi-code multiplexes the first and third orthogonal components to provide a first multiplexed signal, while multi-code multiplexing the second and fourth in-phase components to provide a second multiplexed signal. An I/Q combining part (124) combines the first and second multiplexed signals to provide a combined signal.

Abstract: A wireless communication base station apparatus that can raise the usage efficiency of the frequency resources of the whole system in a multicarrier transmission. In this apparatus, a separating part (103) separates symbols received from a modulating part (102) into symbols to be assigned to a first subcarriers group and into symbols to be assigned to a second subcarriers group. A setting part (106-1) sets the transmission power of the symbols, which are to be assigned to the first subcarriers group, to a power value as calculated by a power calculating part (105), while a setting part (106-2) sets the transmission power of the symbols, which are to be assigned to the second subcarriers group, to a power value as calculated by the power calculating part (105). Thus, the transmission power control is differently performed between the symbols to be assigned to the first subcarriers group and the symbols to be assigned to the second subcarriers group.

Abstract: 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).

Abstract: A link adaptation method and others wherein feedback information amount can be reduced. According to this method, a receiving apparatus (100) calculates, based on a channel matrix, a capacity (C) and a stream ratio (r) that is a ratio of the reception qualities of streams, and then transmits, as feedback information, the calculated capacity (C) and stream ratio (r) to a transmitting apparatus. In the transmitting apparatus (200), the number of transmittable streams, the modulation scheme and the fed-back capacity (C) are used to calculate the encoding ratio (R) and sequence length (S) of spatial multiplexed symbols. Then, the modulation scheme (M1-Mn) of each stream is decided based on the fed-back stream ratio (r) and the sequence length (S) of spatial multiplexed symbols.
