摘要:
A reception apparatus of a time division multiple access (TDMA) system for performing intermittent reception by a reception period of a time slot and a non-reception period of a predetermined number of time slots which follow the reception period and in which reception is suspended includes a symbol clock controller configured to perform symbol synchronization at a timing at which a synchronous word included in the reception period after the non-reception period, and correct a symbol clock frequency of a symbol clock based on a number of time slots and a symbol count value during a previous reception period and the non-reception period following the previous reception period; and a reception period controller configured to correct, after detection of the synchronous word, a reception termination timing of the reception period in which the synchronous word is detected based on the symbol clock with the corrected symbol clock frequency.
