A method for transmit diversity and processing by a receiver in a TD-SCDMA system, comprises steps of: (1) dividing transmitting antennas into two groups, wherein transmit symbols mapped to odd-index code channels of the first group are kept consistent with transmit symbols mapped to even-index code channels of the second group; similarly, transmit symbols mapped to even-index code channels of the first group are kept consistent with transmit symbols mapped to odd-index code channels of the second group; (2) the two groups of antennas performing spread spectrum and scrambling for the transmit symbols respectively with a same spread spectrum code and scrambler to form two groups of data segments, adding different training sequences to the two groups of data segments respectively to form transmit signals while keeping training sequences of all the antennas within the group the same, and transmitting the transmit signals simultaneously from the two groups of antennas after intermediate-frequency radio frequency processing. The present invention avoids interleaving the same transmit symbols in time domain as in the conventional time-space scheme, and reduces the complexity of the receiver equalizer.
