    • A process and system including a detector having a photosensor therein that outputs a signal and a plurality of after-pulse detector devices independently connected to the photosensor via respective pathways. The after-pulse detector devices each detecting an after-pulse in the signal, where the after-pulse represents an after-event in the photosensor triggered from a previous photon generating event. The system further includes a processing device that receives an indication of the detection of the after-pulse from each of the plurality of after-pulse detector devices and determines a relative delay between the respective pathways based on timing the received indications, and includes a memory that stores the relative delay in association with an identification of the corresponding after-pulse detector devices.

    • Disclosed is a modem that uses information from prior modem calls in a current modem call if the current communication line has the same characteristics as the communication line of a prior call. During modem training, a determination is made as to whether the characteristics of the current communication line is substantially similar to the characteristics of a communication line used during at least one prior call. If the characteristics are substantially similar, the stored data mode information from the prior call(s) is used to design a signal constellation for use during the current call's data mode. If the characteristics are not substantially similar, then full modem training is performed and data mode information is stored for use during subsequent calls. In addition to the communication line similarity test, line quality evaluation may also be performed in order to determine whether there has been a change in the quality of the communication line between the current call and prior call(s). If there has been no change in line quality, then a signal constellation is designed using stored minimal signal distance from one or more prior calls. If there has been a change for the better in line quality, then a signal constellation is designed having a smaller minimal signal distance than the one or more prior call's signal constellation. If there has been a change for the worse in line quality, then a signal constellation is designed having a larger minimal signal distance than the one or more prior call's signal constellation.
    • 公开了一种调制解调器,其在当前调制解调器呼叫中使用来自现有调制解调器呼叫的信息,如果当前通信线路具有与先前呼叫的通信线路相同的特性。 在调制解调器训练期间,确定当前通信线路的特性是否基本上类似于在至少一个以前通话期间使用的通信线路的特性。 如果特征基本相似,则来自先前呼叫的存储的数据模式信息被用于设计在当前呼叫的数据模式期间使用的信号星座。 如果特征基本不相似,则执行完全调制解调器训练,并且存储数据模式信息以供在后续呼叫期间使用。 除了通信线路相似性测试之外,还可以执行线路质量评估,以便确定当前呼叫和在先呼叫之间的通信线路的质量是否已经改变。 如果线路质量没有改变,则使用从一个或多个在先呼叫的存储的最小信号距离来设计信号星座。 如果线路质量有所改变,则信号星座被设计为具有比一个或多个在先呼叫的信号星座更小的最小信号距离。 如果线路质量下降了,则信号星座被设计为具有比一个或多个在先呼叫的信号星座更大的最小信号距离。
