Abstract:
An apparatus and method for providing a broadcasting service in a mobile communication system. The apparatus and method can transmit broadcasting service data using orthogonal frequency division multiplexing (OFDM) symbols in the mobile communication system. Broadcasting service data is encoded and modulated. The modulated data is demultiplexed into data streams corresponding to a number of orthogonal frequency subcarriers. The data streams are transformed using Fast Fourier Transform (FFT). The transformed data streams are multiplexed using OFDM. Information with a predetermined length placed in a last part of OFDM data is copied. The copied information is added as a cyclic prefix (CP) to a head part of the OFDM data, and OFDM symbols to be transmitted are generated. The generated OFDM symbols are multiplexed into a forward channel of the mobile communication system, and the multiplexed OFDM symbols are transmitted.
