    • Electronic devices may be provided that contain wireless communication circuitry. The wireless communication circuitry may include radio-frequency transceiver circuitry coupled to multiple antennas. An electronic device may alternate between a sleep mode and a wake mode. During wake mode, the electronic device may monitor a paging channel in a wireless network for incoming paging signals. The device may use a selected one of the multiple antennas in monitoring the paging channel. If received signal quality is satisfactory, the device may maintain use of the selected one of the multiple antennas for subsequent wake period monitoring of the paging channel. If received signal quality falls below a threshold or is otherwise indicated to not be satisfactory, the device may switch to use of a different one of the multiple antennas in monitoring the paging channel. Other criteria may also be used in controlling the switching between antennas for paging channel monitoring.
    • 可以提供包含无线通信电路的电子设备。 无线通信电路可以包括耦合到多个天线的射频收发器电路。 电子设备可以在睡眠模式和唤醒模式之间交替。 在唤醒模式期间,电子设备可以监视无线网络中的呼入寻呼信号的寻呼信道。 该设备可以使用多个天线中所选择的一个来监视寻呼信道。 如果接收到的信号质量令人满意,则设备可以保持对多个天线中所选择的一个天线的使用以用于寻呼信道的随后的唤醒周期监视。 如果接收到的信号质量低于阈值或被指示为不令人满意,则在监视寻呼信道时,设备可以切换到使用多个天线中的不同的天线。 其他标准也可以用于控制用于寻呼信道监测的天线之间的切换。

    • Electronic devices may be provided that contain wireless communication circuitry. The wireless communication circuitry may include radio-frequency transceiver circuitry coupled to first and second antennas. An electronic device may send network access probe signals to a base station in a wireless network. If the base station responds with a corresponding acknowledgement, the electronic device and base station may establish a wireless communication link such as a cellular telephone link. In response to failure to receive the acknowledgement signal from the base station, the electronic device may increase the transmit power of a successive network access probe signal. The electronic device may switch between use of the first and second antennas when transmitting the network access probe signals. The electronic device may alternate between the first and second antennas or may use other antenna usage patterns.

    • A digital subscriber line (DSL) modem that has a canceller digital filter for cancelling crosstalk and RF interference in a received DSL signal is disclosed. The modem includes common-mode sense circuitry and also differential-mode sense circuitry. Samples of the common-mode signal are acquired during a “quiet” period of initialization of the DSL modem, and samples of the differential-mode signal are acquired during live transmission of a DSL signal. An estimate of an autocorrelation function is obtained from the common-mode samples, and a cross-correlation of the common-mode samples and differential-mode samples is also estimated. Digital filter coefficients are derived from these estimates, based on the assumption that the common-mode samples acquired during the “quiet” phase represent crosstalk and RF interference present during differential-mode communications. The digital filter coefficients can also be updated during showtime of the DSL link, using an expanded number of samples of the common-mode and differential-mode signals.
    • 公开了一种具有消除数字滤波器的数字用户线(DSL)调制解调器,用于消除所接收的DSL信号中的串扰和RF干扰。 调制解调器包括共模感测电路和差分模式检测电路。 在DSL调制解调器的初始化的“安静”期间获取共模信号的采样,并且在DSL信号的实时传输期间获取差分模式信号的采样。 从共模样本获得自相关函数的估计,并且还估计共模样本和差模样本的互相关。 基于在“静止”阶段期间获取的共模样本表示在差分模式通信期间存在的串扰和RF干扰的假设,从这些估计导出数字滤波器系数。 数字滤波器系数也可以在DSL链路的显示时间期间使用共模和差模信号的扩展数目的样本进行更新。
