ABSTRACT:
A radio transmitting apparatus and method thereof wherein a guard interval (GI) having a variable length allows a radio receiving apparatus to precisely and easily obtain a symbol synchronization. A GI adding part adds a short GI or a long GI to the head of each of a plurality of data parts. In a case of adding the long GI, the GI adding part copies the symbols of a portion of a second data part, which immediately follows a first data part, including the rear of the second data part, and then adds the copied symbols to the head of the first data part, thereby providing a second GI. Moreover, the GI adding part copies the symbols to a portion of the first data part including the rear thereof, and then adds the copied symbols to the head of the second GI, thereby providing the first GI.
