    摘要: Frames in a variable length frame format which are addressed to a plurality of users are multiplexed and preferably transmitted.Data frames having different lengths are multiplexed on a same time through space division multiple access, but since the multiplexed frames are transmitted while eventually having a same length, when the multiplexed data frames from the access point STA0 are received in the respective communication stations STA1 to STA3 in FIG. 4 or when data simultaneously transmitted from the respective communication stations STA1 to STA3 are received in the access point STA0 in FIG. 5, it is possible to eliminate an operation instability of AGC.

    摘要: A printing apparatus is provided which uses, as a print head, a thermal head having heating elements arrayed in a line perpendicular to the traveling direction of a printing medium. Correspondingly pixel data, at either end, or near the end, of each line of image data going to be printed, data on heat storage in the thermal head (108) is calculated for each line on the basis of data on heat storage in the print head for a preceding line, and the data on heat storage in the print head for each line is compared with predetermined-temperature data. When any of the stored-heat data is larger than the predetermined-temperature data, energy to the heating element (113) is decreased. The image data is printed on the printing medium (104) with the energy for application to the heating element (113) being kept decreased. Thus, even when high-speed printing is done, it is possible to prevent a high temperature from developing at either end of the thermal head, to thereby preventing print-density nonuniformity from resulting in a printed image.

    摘要: A wireless communication apparatus compensates for phase and amplitude imbalances existing among transmit and receive branches, while also preventing likelihood information and SNR estimation error produced by such imbalance compensation. In an apparatus having a plurality of transmit and receive antennas and respective branches for each antenna, a calibration processor multiplies receive signals in each receive branch by antenna calibration coefficients, in order to correct phase and amplitude imbalances existing among the receive branches. A transmit beamforming matrix estimator then estimates a transmit beamforming matrix by using the multiplied receive signals. An estimator then solves for estimated values such as the noise power, likelihood information, and channel waveform equalization values for each receive branch, and in addition, derives a final estimated value that takes the multiplication by correction coefficients into account when averaging the estimated values for each receive branch or when computing a weighted average according to likelihood.

    摘要: A radio communication system, a radio communication control method, a radio communication apparatus, a control method for a radio communication apparatus, and a computer program make it possible to minimize the chance of co-channel interference in a multi-cell environment, and also permit free adjustment of an uplink/downlink ratio. The carrier sense region of a terminal wanting an uplink shares the region used as a directional busy tone region for a terminal wanting an uplink, and the region used as a reference signal transmission region of a terminal wanting a downlink. Furthermore, the carrier sense region of a terminal wanting a downlink shares the region used as a directional busy tone region for a terminal wanting a downlink, and the region used as a reference signal transmission region of a terminal wanting an uplink. If a result of the carrier sense indicates an idle mode, then a reference signal is transmitted.
