| Abstract(in English) | In this paper, the space time transmit diversity (STTD) decoding combined with minimum mean square error combining (MMSEC) equalization is presented for MC-CDMA. The STTD decoding weights that minimize the MSE for each subcarrier before despreading are derived. From computer simulation, it is found that the BER performance of STTD with MMSEC equalization using the weights derived in this paper is always better than that with no diversity and provides the same diversity order as 2-antenna receive diversity with MMSEC equalization but with 3dB performance penalty. The uplink BER performance can also be improved with STTD, however the error floor still exists. |
