    摘要: A video image display apparatus of the flat tube and multi line cathode type of the present invention includes a phosphor screen, and a predetermined number (e.g. 15) of line cathodes for in-turn emitting a predetermined number of horizontal rows of electron beams. Each row has a second predetermined number (e.g. 320) of rod shaped electron beams for together producing one horizontal line of image on the phosphor screen. A vertical deflection means is provided for vertical deflection of the electron beams in turn at one vertically divided segment corresponding to one of the horizontal rows by means of a vertical deflection signal, e.g. a step wave having a saw-tooth wave envelope. The envelope is adjusted so as to be expanded or compressed or level changed, thereby eliminating any undesirable black horizontal band on the screen due to non-uniformity of electrode construction. A uniform raster is thereby obtainable.

    摘要: In a MIMO wireless communication system, the transformation process synthesizes the eigenmodes having a large singular value (i.e. a high effective SNR) and the eigenmodes having a small singular value (i.e. a low effective SNR). Thereby, the former eigenmodes are converted into modes having suppressed effective SNR which do not require a large number of levels of modulation, and the latter eigenmodes are converted into modes having increased effective SNR instead. In a MIMO wireless communication system for eigenmode transmission, a large communication capacity is realized without increasing the number of levels of modulation even in a communication environment capable of achieving a high SNR.

    摘要: The disclosed electromagnetic wave transmission medium prevents electromagnetic leakage during high-power electromagnetic wave transmission. The sheet-form electromagnetic wave transmission medium is configured from a first mesh conductor used in transmission of electromagnetic waves having a first power; and a second mesh conductor used in transmission of electromagnetic waves having a second power. By using two mesh conductors, when said sheet-form electromagnetic wave transmission medium is used, the conduction density of the surface region where electromagnetic waves are extracted to be used for power supply assumes a coarser state than that of the other surface region.

    摘要: In a wireless communication system in which a sending side derives transmit weight vectors based on feedback information and carries out precoding, performance degradation is caused when the channel at the time when the transmit weight vectors are derived and the true channel are different from each other. Along with variations in the channel, the power allocation to a plurality of effective streams formed in MIMO is caused to approach asymptotically to uniform power allocation from the value determined based on the channel state information that the sending side has.
