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.
