Abstract:
A receiving apparatus includes: a receiver receiving a communication signal from a base station and including pilot and sync channel signals in which predetermined data strings continue periodically; a synchronizer acquiring synchronization information for communicating with the base station from the pilot channel signal and, based on the synchronization information, synchronizing with the communication signal; a data acquirer demodulating the sync channel signal from the synchronized communication signal and, by decoding the demodulated sync channel signal, acquiring sync channel signal data; an inference unit inferring a location in the data string of the acquired data by comparing the acquired data with data acquired and held before the acquired data and including the data string; a calculator calculating a time until receiving a next data string head from the inferred location in the data string; and a controller halting the reception of the communication signal based on the calculated time.
