A method for inserting a guard interval in an OFDM or OFDMA mobile communication system and a transmitting apparatus therefore are disclosed. The method for inserting a guard interval in an OFDM or OFDMA mobile communication system comprises rotating a phase of each symbol for a specific symbol stream, converting the phase-rotated symbol stream into a time-domain symbol stream, and performing at least one of copying a rear part of the time-domain symbol stream to insert the rear part of the time-domain symbol stream to the front of the time-domain symbol stream and copying a front part of the time-domain symbol stream to insert the front part of the time-domain symbol stream to the end of the time-domain symbol stream.
