Abstract: Provided is a wireless transmitter capable of accurately specifying the number of multiplexed streams and correctly decoding the data signals when a preamble sequence transmitted from any antenna of a wireless transmitter is detected. In this device, a multiplex count determination unit (101) determines the number of streams used by the device itself from the same number of candidates as the number of spatially multiplexed streams. A sequence group generator (104) forms a plurality of preamble sequences into the same number of groups as the number of candidates, which is the number of streams. A sequence group selector (105) selects the group matching the number of streams determined by the multiplex count determination unit (101) from a plurality of groups. A preamble generator (106) selects the same number of preamble sequences as the number of streams in the group selected by the sequence group selector (105) and generates the preamble sequence used by the device itself.

Abstract: A wireless communication apparatus enabling improved system throughput while limiting the amount of signaling for feedback information. In this apparatus, a setting unit (101) sets transmission power differently for each of a plurality of sub-packets obtained by dividing transmission data (transmission packet). Here, the setting unit (101) sets transmission power differently for each of the plurality of sub-packets so that the total transmission power for the plurality of sub-packets becomes the same as the transmission power that is allocated in advance to the transmission packet that constitutes the plurality of sub-packets. A dividing unit (102) divides the transmission data (transmission packet) into a plurality of sub-packets. Then, a transmitting wireless communication apparatus (100) transmits the plurality of sub-packets in order of sub-packets of higher transmission power (lower error rate).

Abstract: Provided is a mobile communication system capable of obtaining a diversity effect even when a signal received by a relay station has an error in a corporate relay to which time space encoding is applied. In this mobile communication system, when S1 has no error and S2 has an error, a relay station (1) does not perform relay transmission at time t (Null) and relay-transmits S1* to a base station at time t+T. That is, in this case, the relay station (1) relay-transmits at time t+T only S1 to be transmitted at time t when no error is contained in either S1 or S2. Moreover, when S1 has an error and S2 has no error, the relay station (1) relay-transmits S2 at time t and does not perform relay transmission at time t+T (Null). That is, in this case, the relay station (1) relay-transmits only S2 to be transmitted at time t+T at time t if no error is contained in either S1 or S2.

Abstract: A pilot reception power measuring section measures reception power of a pilot symbol and a data section reception power prediction section predicts reception power of data symbols based on the reception power of the pilot symbol. A power comparison section 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 regards the data symbol at the hopping position as colliding with data symbols in other cells. Then, an error correcting decoding section 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 mobile communication system which is capable of, when carrying out mobile communication using a shared channel, increasing in efficiency of transmission timing of the data transmission rate request value to prevent wasteful power consumption and hence reduce power consumption. A mobile station apparatus of the mobile communication system measures CIR of the received signal from a base station apparatus at a CIR measuring section, and decides the data transmission rate request value corresponding to the measured CIR value at a rate request value deciding section. Also, it detects an error of the received signal at a CRC section, and, when no error is found, calculates a difference between the average data transmission rate from a base station apparatus and the data transmission request value at a rate request value transmission controlling section. Then, it transmits the data transmission rate request value to the base station apparatus only when the obtained difference is larger than a threshold value.
