    • A method for enhancing the bit rate and/or margin at which quadrature amplitude modulation (QAM) communication is performed includes the steps of varying a spectral allocation and constellation size with which communication is performed, so as to define a combination of spectral allocation and constellation size at which the bit rate and/or margin are enhanced. The spectral allocation can be varied by varying a stop frequency thereof, while maintaining a substantially constant start frequency, so as to mitigate undesirable high frequency content of the bandwidth. Alternatively, both start and stop frequencies may be varied.
    • 用于增强正交幅度调制(QAM)通信的比特率和/或余量的方法包括以下步骤:改变进行通信的频谱分配和星座大小,以便定义频谱分配和星座的组合 比特率和/或边缘增强的大小。 频谱分配可以通过改变其停止频率而改变,同时保持基本恒定的起始频率,以便减轻带宽的不需要的高频内容。 或者,起始频率和停止频率都可以变化。

    • A programmed illuminated display is provided. The display includes a panel having a plurality of apertures extending therethrough. An optical fiber is provided for each aperture. Each optical fiber has an emitting end aligned with the front face of the panel and a receiving end extending beyond the rear face of the panel. The optical fibers are grouped in a selected manner, and each group of the optical fibers is connected to an LED. The LED's are connected to a control circuit that includes a programmable chip. The chip is programmed to generate a selected firing order for the LED's which in turn direct light through the associated optical fibers for providing a programmed illumination for the display.
    • 提供编程照明显示。 显示器包括具有延伸穿过其中的多个孔的面板。 为每个孔提供光纤。 每个光纤具有与面板的前面对准的发射端和延伸超过面板的后表面的接收端。 光纤以选定的方式分组,并且每组光纤连接到LED。 LED连接到包括可编程芯片的控制电路。 芯片被编程为为LED产生选择的点火顺序,LED依次通过相关联的光纤引导光线,以提供用于显示器的编程照明。
