摘要： The present invention relates to a method for demodulating a BCH by using an SCH in an OFDM system with transmit diversity, and a transmitting apparatus and a receiving apparatus using the same. For this purpose, the present invention provides a transmit diversity transmission method for a transmitting apparatus of a base station that generates an SCH symbol and a BCH symbol, maps the SCH symbol and the BCH symbol to an OFDM signal, converts the OFDM signal into a time domain signal, and transmits the OFDM signal trough a selected antenna among a plurality of antennas. In addition, the present invention provides a method for demodulating a BCH by using an SCH to a mobile station that receives an OFDM signal from the base station, filters an SCH and a BCH from the OFDM signal, converts the OFDM signal to a frequency domain signal, calculates a channel estimation value by using the SCH and the BCH, and coherently demodulates the BCH. According to the present invention, coherent demodulation of a BCH can reduce a frame error generation probability, minimize a channel estimation error due to fading, reduce time for checking the number of antennas of the base station and time for demodulating the BCH, and reduce power consumption.
