摘要： A storage unit stores a preamble signal defined in a legacy system and a preamble signal defined in a MIMO system. A monitoring unit in a transmitting apparatus monitors the existence of any communication apparatus which is not compatible with the MIMO system but accepts the legacy system. A channel characteristics acquiring unit derives the characteristics of a radio channel between the transmitting apparatus and a receiving apparatus. A selector selects a packet format based on a monitoring result obtained by the monitoring unit. The selector also selects where to place LTS, based on the characteristics of wireless channel derived by the channel characteristics acquiring unit.

摘要： A control unit, in cooperation with an interface (IF) unit, a modulation unit and a baseband processing unit, produces a packet signal composed of a plurality of streams. While using as a reference a first known signal assigned to one of the plurality of streams and performing a cyclic timing shift within the first known signal on a first known signal assigned to another stream, the control unit performs a timing shift also on an extensional known signal assigned to a stream where no data is assigned. The amounts of timing shift are given degrees of priority beforehand and for the stream where data signals are assigned the control unit uses the amounts of timing shift in descending degree of priority. For the stream where no data signal is assigned, the control unit uses the amounts of timing shift also in descending degree of priority.

摘要： There are provided a wireless transmitting apparatus and a wireless transmission method that enable reduction of transmission delay of a system by enhancing receiving performance achieved during transmission of network-coded data. A decoding section 18 subjects a demodulated signal to error correction decoding and outputs the decoded signal to a buffer 17. The buffer 17 holds a data packet for a given period of time and outputs the packet to an encoding section 12. An encoding control section 11 controls an encoding rate for transmission data and outputs control information to the encoding section 12. In accordance with control information from the encoding control section 11, the encoding section 12 subjects a data packet to error correction encoding and outputs the coded data packet to a coding section 13. The coding section 13 subjects data sequences that pair up with each other to XOR processing and outputs a processing result to a modulation section 14. A wireless transmission section 15 subjects a modulated signal to transmission processing, such as digital-to-analogue conversion, up-conversion, and amplification, and transmits the signal subjected to transmission processing from an antenna 16 through wireless communication.

摘要： The error rate characteristic in a wireless communication apparatus for relaying communications between a mobile station and a base station is improved. For the modulation level of the resource for network coding, the modulation level from a relay station to the mobile station or the modulation level from the relay station to the base station, whichever is lower, is selected and thus the modulation level becomes QPSK. The relay station preferentially assigns S1 of a systematic bit of high importance, of S1+P1 to the network coding resource. The signal of S1+P1 not assigned to the network coding resource is assigned to the resource for the base station from the relay station. In the example, S1 is assigned to the resource for network coding and P1 is assigned to the resource for the base station from the relay station.

摘要： A wireless communication base station device, whereby precision of propagation path estimation is improved by making possible determination of the contiguity of precoding strings contiguous in frequency regions. In this device, a pre-coding string contiguity determining portion (120) determines whether or not a plurality of pre-coding strings (?) which are input from a pre-coding string calculating portion (119) are contiguous in a frequency region. The pre-coding string contiguity determining portion (120) outputs smoothing possibility data, which indicate determination results, to a control data generating portion (104). The control data generating portion (104) generates control data indicating smoothing possibility data which is input from the pre-coding string contiguity determining portion (120).
