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).

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.

IEEE 802.11ax OFDMA Resource Allocation with Frequency-Selective Fading
Sensors, 2021 This paper studies the usage of orthogonal frequency division multiple access (OFDMA) for uplink transmissions in IEEE 802.11ax networks. OFDMA enables simultaneous multi-user transmissions in Wi-Fi, but its usage requires efficient resource allocation ...

Secured Communication over Frequency-Selective Fading Channels: A Practical Vandermonde Precoding
EURASIP Journal on Wireless Communications and Networking, 2009 We study the frequency-selective broadcast channel with confidential messages (BCC) where the transmitter sends a confidential message to receiver 1 and a common message to receivers 1 and 2.
