Abstract
A digital broadcasting receiving system is provided. A receiving module receives an M number of symbols each carrying an N number of subcarriers of a control signal. A converting module performs FFT on respective ksubcarriers of an isymbol and an (i+1)symbol to generate an (i, k)converted value and an (i+1, k)converted value. A demodulating module performs differential demodulation on the (i, k)and (i+1, k)converted values to generate an (i, k)demodulation value. A combining module soft-combines the (i, 1)demodulation value through the (i, N)demodulation value to generate an iprediction value corresponding to the isymbol. A determining module identifies a synchronization segment in the control signal according to the 1prediction value to the (M−1)prediction value.
