    Abstract: PURPOSE: A device of deciding whether an STTD(Space-Time block coding based Transmit Diversity) is used in a base station and a method thereof are provided to decide whether the STTD is used in the base station having two transmission antennas, so as to perform an exact frequency error correction, thereby improving performance of an entire demodulator. CONSTITUTION: A cell searcher(100) searches a base station where a mobile station is included, through I and Q baseband signals, and obtains a frame timing and a scrambling code of the base station. A scrambling code generator(210) generates the corresponding scrambling code according to the frame timing of the base station with the obtained scrambling code and timing information. The scrambling code is multiplied by the I and the Q baseband signals with the use of a multiplier(215) at correct timing, and is descrambled. A descrambled signal is despread by an accumulator(220). A multiplier(232) multiplies a pilot symbol pattern generated in a CPICH Ant1 symbol pilot generator(230) by the despread signal, and performs de-patternization. A multiplier(242) multiplies a pilot symbol pattern generated in a CPICH Ant2 symbol pilot generator(240) by the despread signal, and performs de-patternization. The first accumulator bank(250) and the second accumulator bank(260) commonly input signals outputted from the two multipliers(232,242).
