Adaptive Space-Frequency Equalization for SC-FDE Systems With Interference [PDF]
IEEE Access, 2019 In this paper, we propose a new space-frequency adaptive equalization (SFAE) method for single carrier frequency domain equalization (SC-FDE) systems that can deal with multipath interference from the highly delay-dispersive channel as well as the ...

Are SC-FDE Systems Robust to CFO? [PDF]
2010 IEEE Wireless Communication and Networking Conference, 2010 This paper investigates the impact of carrier frequency offset (CFO) on Single Carrier wireless communication systems with Frequency Domain Equalization (SC-FDE). We show that CFO in SC-FDE systems causes irrecoverable channel estimation error, which leads to inter-symbol-interference (ISI).
