    • A Pre-distortion mechanism for transmit path non-linearity in xDSL AFE is disclosed in the present invention. The AFE includes a line driver and a pre-distortion signal generator. The line driver receives an input differential signal and generates an output differential signal. The input differential signal includes a first input signal and a second input signal. The output differential signal includes a first output signal and a second output signal. The line driver receives the first input signal to generate the first output signal and receives the second input signal to generate the second output signal. The pre-distortion signal generator is coupled to input ends and output ends of the line driver. The pre-distortion signal generator generates a pre-distortion signal according to a first difference between the first input signal and the first output signal, and a second difference between the second input signal and the second output signal so as to adjust an output state of the analog front-end transmitter having a pre-distortion mechanism.
    • 在本发明中公开了xDSL AFE中的发送路径非线性的预失真机制。 AFE包括线路驱动器和预失真信号发生器。 线路驱动器接收输入差分信号并产生输出差分信号。 输入差分信号包括第一输入信号和第二输入信号。 输出差分信号包括第一输出信号和第二输出信号。 线路驱动器接收第一输入信号以产生第一输出信号并接收第二输入信号以产生第二输出信号。 预失真信号发生器耦合到线路驱动器的输入端和输出端。 预失真信号发生器根据第一输入信号和第一输出信号之间的第一差异产生预失真信号,并产生第二输入信号和第二输出信号之间的第二差值,以便调整输出状态 模拟前端发射机具有预失真机制。

    • Apparatus and methods relating to synchronization of communication equipment are disclosed. Synchronization information received from a bonded communication link can be used to synchronize local and/or remote communication equipment, such as femtocell sites coupled to nodes in a ring network. This may involve isolating a frequency reference signal from a DSL (Digital Subscriber Line) communication link which is a constituent link of a bonded communication link, for example. In a ring network, received synchronization information could be used in synchronizing a locally connected installation of communication equipment, and passed for transmission in the ring network for synchronizing other communication equipment. Such dropping and passing of an analog frequency reference signal could be applied in networks having other topologies as well. At least some embodiments of the invention are applicable to optical links. One or more dedicated wavelengths of an optical link could be used to transfer a frequency reference signal, for example. Other functions, such as quality monitoring, quality reporting, and/or predictive traffic forwarding may be provided in some embodiments.
    • 公开了与通信设备的同步相关的装置和方法。 从绑定通信链路接收的同步信息可用于同步本地和/或远程通信设备,例如耦合到环形网络中的节点的毫微微小区站点。 这可以包括例如从作为绑定通信链路的组成链路的DSL(数字用户线路)通信链路隔离频率参考信号。 在环网中,接收到的同步信息可以用于同步本地连接的通信设备的设备,并且被传递以在环网中进行传输以同步其他通信设备。 模拟频率参考信号的这种丢弃和传递也可以应用于具有其他拓扑的网络中。 本发明的至少一些实施例可应用于光链路。 例如,光链路的一个或多个专用波长可以用于传送频率参考信号。 在一些实施例中可以提供其他功能,例如质量监测,质量报告和/或预测性流量转发。
