    • A television receiver having a signal input terminal supplied with an interlace video signal and a signal coverter connected to the input terminal for converting the interlace video signal to a non-interlace signal to be displayed. The signal converter includes a signal inserting circuit for inserting new line signals between two successive line signals of the interlace signal, the new line signals being formed by interpolating one of the preceding and succeeding line signals in the interlace signal. A three dimensional filter is connected to the signal converter for attentuating vertical and horizontal high frequency components in the non-interlace video signal only when the non-interlace signal includes both of the vertical and horizontal high frequency components.
    • 具有提供隔行扫描视频信号的信号输入端的电视接收机和连接到输入端的信号覆盖器,用于将隔行扫描视频信号转换成要被显示的隔行信号。 信号转换器包括用于在隔行信号的两个相继行信号之间插入新行信号的信号插入电路,通过在隔行扫描信号中插入前一和后一行信号之一来形成新的线信号。 只有当非隔行信号包括垂直和水平高频分量两者时,三维滤波器连接到信号转换器,用于注意非逐行视频信号中的垂直和水平高频分量。

    • When spatial multiplexing is performed to any of a plurality of receiving antennas included in each terminal, it becomes possible to obtain excellent receiving characteristics by combining signals received by all antennas appropriately. A receiving antenna unit 28 receives channel state information from each terminal, a channel matrix H is obtained. A transmit weight/interference coefficient calculation unit 24 calculates a transmit weight and an interference coefficient based on channel matrix. The transmit weight is input to transmit weight multiplication units 17 and 23. The interference generation unit 15 generates an interference signal based on the interference coefficient. An interference subtraction unit 13 subtracts the interference signal from a desired signal. A modulo unit 14 adds a signal so that amplitude of an information signal output from the interference subtraction unit 13 falls within a constant range. A signal multiplexing unit 18 performs spatial multiplexing to the signal performed nonlinear arithmetic.
    • 当对每个终端中包括的多个接收天线中的任何一个进行空间复用时,通过适当地组合由所有天线接收的信号,可以获得良好的接收特性。 接收天线单元28从每个终端接收信道状态信息,获得信道矩阵H. 发送权重/干扰系数计算单元24基于信道矩阵来计算发送权重和干扰系数。 发送权重被输入到发送权重乘法单元17和23.干扰生成单元15基于干扰系数产生干扰信号。 干扰减除单元13从期望的信号中减去干扰信号。 模数单元14添加信号,使得从干扰减除单元13输出的信息信号的幅度落在一定范围内。 信号复用单元18对所执行的非线性运算进行空间复用。
