Joint effect of space-time transmit diversity and equalization on single carrier transmission

چکیده
Abstract In a frequency-selective fading channel, the performance of single-carrier (SC) transmission significantly degrades due to severe inter-symbol-interference (ISI). In this paper, delay transmit diversity and space-time transmit diversity (STTD) as transmit diversity are combined with minimum mean square error (MMSE) frequency-domain equalization achieving frequency diversity effect while suppressing inter-symbol-inference (ISI) and its bit error rate (BER) performance is evaluated by computer simulation. It is found by computer simulation that BER performance achievable with joint use of frequency-domain equalization and transmit/receive antenna diversity can be significantly improved in a severe frequency-selective fading channel.

Single-Carrier Frequency-Domain Equalization for Orthogonal STBC over Frequency-Selective MIMO-PLC channels
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...

Abstract: Orthogonal frequency division multiplexing (OFDM) combined with time division multiplexing (TDM) can bridge the conventional OFDM and single carrier (SC) transmission by using minimum mean square error (MMSE) frequencydomain equalization (FDE). The channel frequency-selectivity can be exploited by MMSE-FDE to improve the bit error rate (BER) performance. A much better BER performance ...
متن کاملTransmit Multi-Block FDE for Space-Time Block Coded Joint Transmit/Receive Diversity in a Quasi-Static Fading Channel
In this paper, we propose a transmit multi-block frequency-domain equalization (MB-FDE) for frequency-domain spacetime block coded joint transmit/receive diversity (FD-STBC-JTRD). Noting that a STBC codeword consists of multiple coded blocks, the transmit MB-FDE uses the multiple transmit FDE weight matrices, each associated with each coded block. Both single-carrier (SC) transmission and ortho...

Abstract A modification of transmit filtering in single-carrier (SC) transmission contributes to an improvement of system performance in terms of peak-to-average power ratio (PAPR) and bit error rate (BER). Using minimum mean-square error based frequency-domain equalization (MMSE-FDE) at the receiver can combat the problem of inter-symbol interference (ISI) arising from channel frequency-select...
