Abstract: A communication system implements detection of bad frames of information by utilizing multiple bit correction thresholds. Equipment used within the communication system adapts to different signaling environments by dynamically altering the bit correction threshold based on a history of the number of consecutive bad frames of information that have been previously erased and the number of bits corrected by a channel decoder (202). By implementing this dynamic bit correction threshold, sufficent bad frame indication (BFI) detection and receiver sensitivity can be obtained simultaneously, which results in an improved perceived audio quality to the end user.

Abstract translation: 通信系统通过利用多个比特校正阈值来实现对坏帧信息的检测。 在通信系统中使用的设备通过基于先前已被擦除的连续坏信息的数量的历史和由信道解码器（202）校正的比特数来动态地改变比特校正阈值来适应不同的信令环境。 通过实现这种动态位校正阈值，可以同时获得足够的坏帧指示（BFI）检测和接收机灵敏度，这样可以提高对最终用户的感知音质。
