ABSTRACT:
A transmission apparatus for a DS/CDMA system including a multiple-input multiple output MIMO antenna system is disclosed. The apparatus includes a transmitter for transmitting data by applying a different scramble code to each transmitted data through a plurality of transmitting antennas. The apparatus also includes a receiver for receiving the transmitted data by obtaining a diversity gain based on the maximum order of the diversity in order to effectively detect the data. The present invention achieves an excellent detection performance by receiving data with a full order of diversity, which is a multiple of the number of receiving antennas and the number of multipath, without complicated operation such as a decision feed equalizer.
