Abstract: PURPOSE: A digital broadcasting transceiver is provided to prevent a fault in AGC(Auto Gain Control) by holding AGC in an FEF(Future Extension Frame) region. CONSTITUTION: A frequency converting unit(41) converts an RF(Radio Frequency) signal of an RF AGC amplification unit(20) into an IF(Intermediate Frequency) signal. A first AGC detection unit(42) detects the IF signal level. An RF AGC processing unit(100) supplies a first AGC control voltage. An ADC(Analog to Digital Converter)(210) performs A/D conversion of the IF signal. An FEF(Future Extension Frame) detection unit(230) detects the FEF region in the A/D converter. The FEF detection unit controls the AGC hold in the RF AGC processing unit.

Abstract: PURPOSE: A receiving circuit of the satellite digital video broadcasting system is provided, which integrates the duplicated auto correlation calculation circuits into one circuit, thereby the complexity of circuit is lowered conspicuously. CONSTITUTION: A common auto correlation unit(120) multiplies the auto correlation coefficient to the synchronized receiving symbol. A frame synchronization unit(130) detects the SOF(Start Of Frame) from the self correlation by receiving symbol. The SOF is the synchronization word indicating the beginning of frame. A frequency synchronization unit(140) presumes the frequency error information from the self correlation by receiving symbol and the SOF. An SNR estimation unit(150) presumes the SNR(Signal to Noise Ratio) from the self correlation by receiving symbol and the SOF.
