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 kth subcarriers of an ith symbol and an (i+1)th symbol to generate an (i, k)th converted value and an (i+1, k)th converted value. A demodulating module performs differential demodulation on the (i, k)th and (i+1, k)th converted values to generate an (i, k)th demodulation value. A combining module soft-combines the (i, 1)th demodulation value through the (i, N)th demodulation value to generate an ith prediction value corresponding to the ith symbol. A determining module identifies a synchronization segment in the control signal according to the 1st prediction value to the (M−1)th prediction value.
