摘要： Method and apparatus for signal detection in dynamic channels with high carrier frequency offset are provided. A coherent detector and a non-coherent detector are operated in parallel on a block of samples of an input signal to determine respective time offset candidates of the input signal. The time offset candidate obtained from the non-coherent detector is used to determine a frequency offset candidate of the input signal.

摘要： An example method for notifying a battery-powered device of the presence of high priority broadcast content while enabling the device to conserve battery power includes generating a high priority broadcast signal. The signal includes a high priority symbol identifier for informing the battery powered device to switch from an idle state to an acquisition state to inspect the remainder of the high priority broadcast signal. The signal further includes a high priority indication symbol for informing the battery powered device to transition to an active state from the acquisition state to receive high priority broadcast content before returning to the idle state. The signal further includes a timing symbol for informing the battery powered device of the minimum time period until a next a high priority broadcast signal should be expected, enabling the battery powered device to remain in the idle state until the next high priority broadcast signal.
摘要翻译： 用于通知电池供电设备存在高优先级广播内容的实例方法同时使设备节省电池电力包括生成高优先级广播信号。 信号包括用于通知电池供电设备从空闲状态切换到获取状态的高优先级符号标识符，以检查高优先级广播信号的剩余部分。 信号还包括高优先级指示符号，用于通知电池供电设备从获取状态转换到活动状态，以在返回到空闲状态之前接收高优先级的广播内容。 信号还包括用于通知电池供电设备的最小时间段的定时符号，直到下一个应该预期的高优先级广播信号，使得电池供电设备能够保持在空闲状态直到下一个高优先级广播信号。
