Abstract
A digital broadcasting receiver reduces the amount of operations in timing synchronization processing while reducing circuit scale and power consumption. Selective data extraction thins out and band-limits input data from demodulation data of phase reference symbols subjected to known modulation as synchronizing signal to reduce the number of data, so that the amount of required operations in phase correcting, IDFT and peak detecting can be reduced.
