    • Methods and apparatus are disclosed for using error detection techniques, such as Forward Error Correction techniques, to predict the degradation below a certain threshold of an ability to accurately convey information on a communication channel, for example, to predict a failure of the communication channel. In response, transmission and/or reception of information on the channel may be adapted, for example, to prevent the degradation below the threshold, e.g., prevent channel failure. Predicting the degradation may be based, at least in part, on data transmission error information corresponding to one or more blocks of information received on the channel and may include determining an error rate pattern over time. Based on these determinations, the degradation below the threshold may be predicted and the transmission and/or reception adapted. Adapting may include initiating use of a different error encoding scheme and/or using an additional communication channel to convey information.
    • 公开了使用错误检测技术(例如前向纠错技术)的方法和装置来预测在通信信道上准确地传送信息的能力的某一阈​​值以下的劣化,例如预测通信信道的故障。 作为响应,信道上的信息的传输和/或接收可以适应于例如防止劣化到阈值以下,例如防止信道故障。 可以至少部分地基于与信道上接收的一个或多个信息块相对应的数据传输错误信息来预测劣化,并且可以包括随时间确定错误率模式。 基于这些确定,可以预测低于阈值的劣化,并且传输和/或接收适应。 适应可以包括启动使用不同的错误编码方案和/或使用附加通信信道来传达信息。
