| Abstract: | According to the analysis of special nature of the burst-mode signal and a variety of detection methods,a method based on the DC-coupled is proposed in order to detect the burst-mode signal.In this paper,the circuits of the burst-mode signal receiver are introduced,especially the Trans Impedance Amplifier(TIA) circuit and the automatic power control circuit(ATC).At last,an example in application of China Mobile Multimedia Broadcasting(CMMB) is given. |
