摘要：
PURPOSE: A broadcasting signal detecting device and a method thereof are provided to distinguish DRM+ (Digital Radio Mondiale Plus) broadcasting and FM broadcasting signal in the hybrid broadcasting mode. CONSTITUTION: A broadcasting signal detecting device (10) comprises a guard-interval corrector (110), a reference signal generator (120), and a signal determining unit (130). The guard-interval corrector normalizes the received signal which is performed guard-interval correlation operation and outputs the correlation signal. The reference signal generator takes the average for the predetermined observation symbol period after performing correlation operation between the current sample and the previous sample of the received signal which is FM signal or DRM+ signal. The reference signal generator generates the reference signal by normalizing the average of for the observation symbol period using the mean power of the current sample and the previous sample. The signal determining unit detects the maximum value of the reference signal and judges the received signal is FM signal if the maximum value of the reference signal exceeds the predetermined threshold.

摘要（中）：
目的：提供广播信号检测装置及其方法，以区分混合广播模式中的DRM +（Digital Radio Mondiale Plus）广播和FM广播信号。 构成：广播信号检测装置（10）包括保护间隔校正器（110），参考信号发生器（120）和信号确定单元（130）。 保护间隔校正器将执行保护间隔相关运算的接收信号归一化，并输出相关信号。 参考信号发生器在执行当前采样和作为FM信号或DRM +信号的接收信号的先前采样之间的相关操作之后，获取预定观测符号周期的平均值。 参考信号发生器通过使用当前样本和先前样本的平均功率标准化观察符号周期的平均值来生成参考信号。 信号确定单元检测参考信号的最大值，并且如果参考信号的最大值超过预定阈值，则判断接收信号是FM信号。 （附图标记）（110）保护间隔校正器; （120）参考信号发生器; （130）信号确定单元
