چکیده
Abstract Single-carrier (SC) transmission is an appropriate transmission scheme for uplink transmission because of its low peak-to-average power ratio (PAPR). Spread spectrum (SS) transmission achieves higher frequency diversity gain and hence improves the bit error rate (BER) performance. The authors have recently proposed SC with frequency-domain spread spectrum (SC-FDSS) transmission with orthogonal code multiplexing, where spreading and de-spreading are conducted in frequency domain. In this paper, we extend the single-user SC-FDSS to multi-user SC-FDSS called SC with frequency-domain code division multi-access (SC-FD-CDMA). BER and PAPR performances are evaluated and compared to direct-sequence code division multi-access CDMA (DS-CDMA) and SC with frequency division multi-access (SC-FDMA) Keyword Single-carrier (SC) transmission, spread spectrum, code division multi-access (CDMA), uplink transmission

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...

In this paper, we describe a novel type of cyclic prefix assisted single carrier CDMA system with Frequency Domain Equalization (FDE) and MIMO Multiplexing. The proposed method is referred to as MIMO SC/FDE CDMA. Multipath Interference can be mitigated by inserting cyclic prefix at the transmitter. Furthermore, we use different scrambling codes to separate different transmit antennas. At the re...

Single-carrier (SC) multiple access is a promising uplink multiple access technique because of its low peak-to-average power ratio (PAPR) property and high frequency diversity gain that is achievable through simple one-tap frequency-domain equalization (FDE) in a strong frequency-selective channel. The multiple access capability can be obtained by combining either frequency division multiple ac...
متن کاملUplink BER Performance Comparison of Single-carrier Multi-access and Multi-carrier Multi-access
Abstract The downlink bit error rate (BER) performances of DSand MC-CDMA in a frequency-selective fading channel can be significantly improved by the use of frequency-domain equalization (FDE) based on minimum mean square error (MMSE) criterion. However, the uplink BER performance degrades due to strong multi-user interference (MUI) since different users’ signals go through different channels a...

In this paper, we propose a low complexity receiver structure for Single-input Multiple-output (SIMO) downlink cyclic prefix CDMA (CP-CDMA) systems. It employs an interference cancellation scheme to suppress the interference caused by the multipath fading channel. Also, the proposed scheme is developed for Multiple-input Multiple-output (MIMO) CP-CDMA system. All filters in the proposed receive...
