A receiving apparatus that can properly determine the position of an effective symbol included in a received signal is provided. A receiver acquires a signal from a sending apparatus that transmits a signal into which a guard interval which is a replica of at least part of an effective symbol is inserted between the effective symbol and another effective symbol. A timing detector finds a correlation between the received signal and a signal obtained by shifting the received signal in a time direction, detects timing at which a maximum correlation value is obtained, and determines that timing which is predetermined time (>0) away from the timing detected is a position of an effective symbol included in the received signal.
