Patent ID: 6941151

Claim:
A receiving apparatus for receiving a radio signal, each frame of which includes a series of n (integer equal to or greater than 1) time slats and a frame guard period added to the series of n time slots to suppress a frame loss due to interference, each time slot including an effective symbol period and a guard period added to the effective symbol period, the receiving apparatus comprising: a front-end reception processing unit for receiving the radio signal; a synchronization position detector for detecting a starting position of an effective symbol period in the received signal; a timing generator for controlling an operation timing of a functional block, on the basis of synchronization position information supplied from the synchronization position detector; a reception windowing unit for extracting only an effective symbol period including no time guard period and no frame guard, under the control of the timing generator; and a back-end reception processing unit for reproducing desired information from a windowed signal supplied by the reception windowing unit.
