    摘要： A wireless communication system includes: a multiple number of mobile station apparatuses that transmit code bits obtained by applying error-correction coding to information bits; a relay station apparatus that receives code bits from the multiple mobile station apparatuses, applies network coding on the code bits and transmits the network-code bits; and a base station apparatus that receives and decodes the code bits and the network-code bits, wherein the base station apparatus, when decoding the received code bits, performs iteration decoding by regarding the received code bits as a serially concatenated code of network coding and error correction coding. Accordingly, decoding is performed by regarding the network code and the error correction code as a serial concatenated code, it is possible to obtain diversity with a simple configuration.

    摘要： In using frequency selective precoding to a multicarrier signal, notification is provided with control information. A radio transmitter, divides a frequency signal into a plurality of clusters, arranges each of the divided clusters on a frequency domain and multiplies each of the clusters by a precoding matrix, limits the number of precoding matrices to be selected based on the relationship between a precoding matrix to be multiplied to any of the clusters and a precoding matrix to be multiplied to any of the other clusters. The number of precoding matrices to be selected is limited based on the relationship between a precoding matrix to be multiplied to any one of the clusters and a precoding matrix to be multiplied to another cluster neighboring thereto. The number of precoding matrices to be selected is limited based on frequency correlation between any one of the clusters and another cluster neighboring thereto.

    摘要： In SU-MIMO, even when the channel state of one antenna is poor, an error ratio is improved by obtaining a transmission antenna diversity effect. A transmission apparatus 100 that has a plurality of antennas 108-1 to 108-Ntx and transmits a signal according to a MIMO (Multiple Input Multiple Output) system includes a DFT part 111 for precoding transmission data and a spectrum division part 112 for dividing a spectrum output from the DFT part 111. The divided spectrums are transmitted from the different antennas 108-1 to 108-Ntx, respectively.
