ABSTRACT:
The present invention relates to a transmit diversity method of a mobile communication system and a base station transmitting apparatus using the same. A first code and a second code that is diversity-encoded from the first code are generated, and transmit symbols are spread with the first code and the second code. A first transmit symbol spread with the first code and a second transmit symbol spread with the second code are mapped to symbols in frequency and time domains in a frame and transmitted through antennas. Therefore, various diversity techniques can be provided to the mobile communication system, and the diversity technique is not restricted to symbols transmitted to the same mobile station and can also be applied to a 1-bit channel.
