Review of Single Carrier FDE Performance Enhancement Techniques
نویسنده
چکیده
Single-carrier (SC) block transmission with cyclic prefix (CP) has several advantages that has been seen in this paper. The aim of this paper to improved the performance of SC-FDE multi-antenna SC-FDE by using cyclic-delay diversity (CDD) and Alamouti signaling. Analysis characterizes the diversity, it shows that diversity depends on the antenna configuration, channel memory, data block length and data transmission rate. Full diversity is available to both CDD and Alamouti signaling below a certain rate threshold, while at higher rates their diversity diminishes. This paper shows that at high data rates the Alamouti signaling provides twice the diversity of SISO SC-FDE, while CDD diversity degenerates to the diversity of the SISO SC-FDE.

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...

Minimum mean square error frequency-domain equalization (MMSE-FDE) can achieve a good performance in the case of single-carrier (SC) transmission in a frequencyselective fading channel. The conventional FDE requires the insertion of guard interval (GI) to avoid the inter-block interference (IBI). However, the GI insertion reduces the throughput. Recently, overlap FDE which requires no GI insert...

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...

Recently, frequency-domain equalization (FDE) has been attracting much attention as a way to improve single-carrier (SC) signal transmission in a frequency-selective wireless channel. Since the SC signal spectrum is spread over the entire signal bandwidth, FDE can take advantage of channel frequency-selectivity and achieve the frequency diversity gain. SC with FDE is a promising wireless signal...

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...
