    • When an antenna receives a signal, the signal is inputted to delayers through a frequency converter, A/D converters, quadrature demodulators, filters and simultaneously is inputted to a MUX. The receiving signal inputted to the MUX is transmitted to an interference canceler panel, and the interference canceler panel generates both an interference replica signal and a symbol replica signal. The interference canceler panel demodulates the receiving signal for a channel corresponding to the symbol replica signal using both the interference and symbol replica signals. The interference replica signal generated by the interference canceler panel is transmitted to a transmitting/receiving panel and is inputted to interference elimination units. The interference elimination units eliminates interference components by subtracting the interference replica signal from the receiving signal delayed by the delayers and transmits the signal to a baseband signal processing panel.
    • 当天线接收信号时,该信号通过变频器,A / D转换器,正交解调器,滤波器输入到延迟器,同时被输入到MUX。 输入到MUX的接收信号被发送到干扰消除器面板,并且干扰消除器面板产生干扰复制信号和符号复制信号。 干扰消除器面板使用干扰和符号复制信号来解调对应于码元复制信号的信道的接收信号。 由干扰消除器面板生成的干扰复制信号被发送到发送/接收面板,并被输入到干扰消除单元。 干扰消除单元通过从由延迟器延迟的接收信号中减去干扰复制信号来消除干扰成分,并将该信号发送到基带信号处理面板。

    • An improved multi-bit memory cell includes a storage capacitor and a switching element coupled to one of the terminals of the capacitor. The switching element includes a first switching component having a positive threshold, and a complementary switching component having a negative threshold. Because the switching element is constructed in this manner, noise generation caused by activation of the switching components is significantly reduced, and cut-off effects are eliminated. Both of these factors contribute to the memory cell's ability to store more bits of information than prior art memory cells.
    • 改进的多位存储单元包括存储电容器和耦合到电容器的一个端子的开关元件。 开关元件包括具有正阈值的第一开关元件和具有负阈值的互补开关元件。 由于以这种方式构成开关元件,所以由于开关元件的激活引起的噪声产生明显地降低,从而消除了截止效应。 这两个因素都有助于存储单元存储比现有技术存储器单元更多位信息的能力。
