Performance Evaluation for Frequency-domain Pre-equalization with Space-Time block coding Transmit/Receive diversity in DS-CDMA Mobile Radio

چکیده
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 discussed. In this paper, we propose a new transmit/receive diversity technique that jointly uses pre-FDE transmit diversity and two-antenna receive diversity, called frequency-domain space-time block coded transmit/receive diversity (STTRD) for DS-CDMA transmissions. Its bit error rate (BER) performance is evaluated by computer simulation and compared to space-time coded transmit diversity (STTD) jointly used with antenna receive diversity.

Abstract 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 th...

In this paper we propose a new space diversity scheme for broadband PLC systems using orthogonal space-time block coding (OSTBC) transmission combined with single-carrier frequency-domain equalization (SC-FDE). To apply this diversity technique to PLC channels, we first propose a new technique for combining SC-FDE with OSTBCs applicable to all dispersive multipath channels impaired by impulsive...

متن کاملSpace-time block coding for single-carrier block transmission DS-CDMA downlink
The combination of space–time block coding (STBC) and direct-sequence code-division multiple access (DS-CDMA) has the potential to increase the performance of multiple users in a cellular network. However, if not carefully designed, the resulting transmission scheme suffers from increased multiuser interference (MUI), which dramatically deteriorates the performance. To tackle this MUI problem i...
