摘要： A synchronization method is provided. In the synchronization method, a first mutual ranging symbol is transmitted to at least one other subscriber station. A second mutual ranging symbol is received from the other subscriber station. Uplink synchronization information is controlled on the basis of the second mutual ranging symbol.

摘要： Disclosed are an apparatus and a method for detecting a broadcasting signal. The signal detecting apparatus according to the exemplary embodiment of the present invention includes: a reference signal generator outputting a reference signal acquired by performing a correlation calculation between a current sample and a previous sample of a received signal which is an FM signal or a digital radio mondiale plus (DRM+) signal and then normalizing a result of the correlation calculation; and a discriminator detecting a maximum value of the reference signal and judging that the received signal is the FM signal when the maximum value of the reference signal is more than a predetermined threshold.
