    • A multi-tone transceiver including: a channel controller and a plurality of components forming a transmit path and a receive path. The channel controller configured to determine bit-loading for each successive symbol or tone set based on a 1st noise margin target for a first subset of tones in each tone set dedicated to transport of a robust communications channel (RCC) and based on a 2nd noise margin target less than the 1st noise margin target for remaining tones in each tone set dedicated to a standard communications channel (SCC). The plurality of components forming the transmit and receive paths are responsive to the channel controller to select for data modulated on a given tone at least one of smaller constellations and higher gain scaling levels when the given tone corresponds to an RCC tone as compared to an SCC tone, whereby the first set of tones dedicated to the RCC exhibit greater immunity to noise variations than the remaining tones dedicated to the SCC.
    • 一种多音调收发器,包括:信道控制器和形成发送路径和接收路径的多个组件。 信道控制器,被配置为基于专用于传输鲁棒通信信道的每个音调集合中的第一音调子集,确定每个连续符号或音调集合的比特加载(...) RCC),并且基于小于专用于标准通信信道(SCC)的每个音调集合中的剩余音调的小于噪声余量目标的2 nd nd噪声容限目标。 形成发送和接收路径的多个组件响应于信道控制器,以便在给定音调对应于RCC音调与SCC相比时,为给定音调调制的数据中的至少一个较小星座和较高增益缩放级别 音调,由此专用于RCC的第一组音调比专用于SCC的剩余音调具有更大的对噪声变化的抗扰度。

    • A plasma processing chamber and methods for operating the chamber are provided. An exemplary chamber includes an electrostatic chuck for receiving a substrate and a dielectric window connected to a top portion of the chamber. An inner side of dielectric window faces a plasma processing region that is above the electrostatic chuck and an outer side of the dielectric window is exterior to the plasma processing region. Inner and outer coils are disposed above the outer side of the dielectric window, and the inner and outer coils are connected to a first RF power source. A powered grid is disposed between the outer side of dielectric window and the inner and outer coils. The powered grid is connected to a second RF power source that is independent from the first RF power source.
