摘要：
A device and method for counting bit errors in the received signal in digital communication, and a device and method for judging whether received signal is aural signal or control signal and for outputting identification signal, the number of errors, and decoded signal. Generally in bit error counters, there is a problem that an exact error rate cannot be calculated if an error that is incorrectable is included in a decoded signal. To overcome the problem, a status monitoring unit (22) is provided, which outputs a predetermined error rate utilizing information in the decoding process if an error is included in the decoded signal. Further, an error detection unit (28) is provided, which outputs a predetermined error rate if an error is included in the decoded signal. In identification devices, there is a problem that signal cannot be identified if an error that is undetectable is included, because the kind of the input signal is identified based on the result of error detection. To solve this problem, a signal identification unit (1206) is provided, which identifies the input signal based on the error detection result, the decoding result, and the number or errors.
摘要（中）：
一种用于对数字通信中的接收信号中的比特错误进行计数的装置和方法，以及用于判断接收信号是听觉信号还是控制信号并用于输出识别信号，误差数目和解码信号的装置和方法。 通常在位错误计数器中，存在如下问题：如果解码信号中包含不正确的错误，则不能计算精确的错误率。 为了克服这个问题，提供了状态监视单元（22），如果在解码信号中包含错误，则利用解码处理中的信息输出预定的错误率。 此外，提供错误检测单元（28），如果解码信号中包含错误，则输出预定的错误率。 在识别装置中，由于根据错误检测结果来识别输入信号的种类，所以存在不能识别出不可检测的误差的信号的问题。 为了解决这个问题，提供了一种信号识别单元（1206），其基于错误检测结果，解码结果以及数量或错误来识别输入信号。
