Comparison of Achievable Rates of OFDM and Single Carrier Communication Systems
Tsinghua Science and Technology, 2012 This paper presents a theoretical comparison of a single carrier system and a multi-carrier system through an analysis of the achievable rate under frequency selective fading with channel state information at the receiver.

Performance Analysis of MIMO STBC System in Flat Fading and Frequency Selective Fading Channels
Journal of Electrical, Electronics and Informatics, 2019 Multiple Input Multiple Output (MIMO) technology is a technique that can be used to overcome multipath fading. The multipath fading is caused by signals coming from several paths that experience different attenuations, delays and phases.

New OSTBC for Blind Channel Estimation and Tracking in MIMO-OFDM Systems
Journal of Telecommunications and Information Technology, 2019 Applying orthogonal space time block coding (OSTBC) to multiple-input multiple-output (MIMO) systems helps reduce receiver complexity. However, this approach has been applied only to flat fading channels, as when the channel is a frequency selective ...

Transmitter Selection for Secrecy in a Frequency Selective Fading Channel with Unreliable Backhaul [PDF]
2021 IEEE 93rd Vehicular Technology Conference (VTC2021-Spring), 2021 In this paper, a communication network using single carrier with cyclic prefix modulation over frequency selective channels is considered, where an access point provides connectivity to a legitimate destination through multiple transmitters with unreliable backhaul links in the presence of an eavesdropper.

Distributed sensing using frequency-selective fading
Optics ExpressThe fading phenomenon in optical time-domain reflectometry is regarded as a detrimental process that degrades measurement performance. In this study, we investigate the fading behavior of coherent Rayleigh backscattering. Using this characterization, we propose and demonstrate that fading can be utilized for distributed sensing.

Least Mean Square Frequency Domain Equalization for MIMO SC-FDMA System
Zanco Journal of Pure and Applied Sciences, 2019 Because single carrier modulation has low peak average power ratio (PAPR), it is used instead of multicarrier modulation in uplink transmission in Long Term Evolution (LTE).
