    摘要: When an error correction decoding unit 26 of a data reception device 2 fails in error correction decoding of a codeword, an MIMO processing unit 15 of a data transmission device 1 deforms transmitted codewords according to a predetermined rule, and transmits the codewords, and the error correction decoding unit 26 of the data reception device 2 reproduces data by using the deformed codewords. As a result, not only the noise but the interference wave components can be reduced, and the success rates of the demodulation and error correction decoding can be improved greatly.

    摘要: Within a communication system in which an ARQ control is exercised, in a transmission-side communication apparatus 11, a transmission scheduling unit 113 determines a transmission amount to be transmitted to a reception-side communication apparatus 21; an erasure correction encoding unit 112 performs an erasure correction encoding process on an information packet group that is made up of a plurality of packets to be transmitted so as to generate one or more erasure correction coded packets that fit the transmission amount instructed by the transmission scheduling unit 113 and specifies the one or more erasure correction coded packets as a unit of delivery confirmation; and a modulating unit 115 transmits a transmission data signal that has been generated by performing a predetermined modulation process on each of the erasure correction coded packets. In the reception-side communication apparatus 21, an erasure correction decoding unit 213 generates the information packet group by performing an erasure correction decoding process on the received signal and also generates, in the case where the erasure correction decoding process has successfully been performed, a delivery confirmation signal for each unit of delivery confirmation, the delivery confirmation signal indicating that reception of the transmission data signal has been completed, so that the generated delivery confirmation signal is transmitted to the transmission-side communication apparatus 11.

    摘要: A method selects antennas in an OFDMA wireless network including a base station and a mobile station. The mobile station measures a channel state of a downlink in a downlink subframe using different subsets of available antennas, and selects a subset of receive antennas for downlink reception based on the channel states between the base station and the different subsets of antennas at the mobile station. The base station measures the channel state in an uplink using an uplink subframe received in the base station from the mobile station, and selects a subset of transmit antennas for mobile station's uplink transmission based on the channel states between the base station and different subset of antennas at the mobile station.

    摘要: An apparatus for dewatering primary dewatered sludge pieces conditioned with dewatering powders comprises: a first member having a recess and a path communicating with the recess, a fluid-tight diaphragm mounted over the recess thereby defining a fluid chamber with which the path communicates, a second member having a filtrate member, and a filter member provided over the filtrate chamber. At least one of the first member and the second member is mounted to bring them into fluid-tight contact with each other, and the primary dewatered sludge pieces into a cavity defined by the diaphragm and the filter member. A pressure fluid then is fed to the fluid chamber, thereby isostatically compressing the primary dewatered sludge pieces to remove the water contained therein without substantially destroying the inner structures of the primary dewatered sludge pieces. Because of this isostatic pressure exerted by the diaphragm, the sludge pieces are compressed highly uniformly, resulting in high dewatering efficiency.
