Joint Frequency-domain Equalization and Multiple Transmit/Receive Antenna Diversity for DS-CDMA
نویسندگان
چکیده
Frequency-domain equalization used in MC-CDMA can be applied to the reception of DS-CDMA signals. Further performance improvement can be attained by the additional use of multiple transmit/receive antenna diversity. The BER performance improvement attainable by the joint use of frequency-domain equalization and multiple transmit/receive antenna diversity in a frequency-selective fading channel is evaluated by computer simulation. In this paper, delay transmit diversity (DTD) is used as transmit diversity. It is found that DTD is effective to improve the BER performance in a fading channel with weak frequency-selectivity.

Performance Evaluation for Frequency-domain Pre-equalization with Space-Time block coding Transmit/Receive diversity in DS-CDMA Mobile Radio
Abstract Recently, frequency-domain pre-equalization (pre-FDE) transmission has been attracting attention for improving the SC transmission (e.g., DS-CDMA) performance in a frequency-selective fading channel. Antenna diversity reception is also a well-known technique for improving the transmission performance. However, so far the joint use of pre-FDE and the receive diversity has not been discu...

متن کاملJoint Frequency-domain Equalization and Antenna Diversity Combining for Orthogonal Multicode DS-CDMA Signal Transmissions in A Frequency-selective Fading Channel
Orthogonal multicode direct sequence code division multiple access (DS-CDMA) has a flexibility in offering various data rate services. However, in a frequency-selective fading channel, the bit error rate (BER) performance is severely degraded since othogonality among spreading codes is partially lost. In this paper, we apply frequency-domain equalization and antenna diversity combining, used in...

Frequency-domain equalization (FDE) can take advantage of the frequency-selectivity of the channel to improve the transmission performance in a frequency selective fading channel. To further improve the transmission performance, the transmit diversity technique can be used. Cyclic delay transmit diversity (CDTD) can strengthen the frequencyselectivity while space-time transmit diversity (STTD) ...

Frequency-domain equalization (FDE) based on the minimum mean square error (MMSE) criterion can provide a better bit error rate (BER) performance than rake combining. To further improve the BER performance, cyclic delay transmit diversity (CDTD) can be used. CDTD simultaneously transmits the same signal from different antennas after adding different cyclic delays to increase the number of equiv...
