TLDR
This article surveys frequency domain equalization (FDE) applied to single-carrier (SC) modulation solutions and discusses similarities and differences of SC and OFDM systems and coexistence possibilities, and presents examples of SC-FDE performance capabilities.Abstract:
Broadband wireless access systems deployed in residential and business environments are likely to face hostile radio propagation environments, with multipath delay spread extending over tens or hundreds of bit intervals. Orthogonal frequency-division multiplex (OFDM) is a recognized multicarrier solution to combat the effects of such multipath conditions. This article surveys frequency domain equalization (FDE) applied to single-carrier (SC) modulation solutions. SC radio modems with frequency domain equalization have similar performance, efficiency, and low signal processing complexity advantages as OFDM, and in addition are less sensitive than OFDM to RF impairments such as power amplifier nonlinearities. We discuss similarities and differences of SC and OFDM systems and coexistence possibilities, and present examples of SC-FDE performance capabilities.read more

Asymptotically optimal low-complexity single-carrier frequency-domain equalizer with time-domain noise prediction in data-like co-channel interference
Minuk Kim,Joon Ho Cho +1 more
TL;DR: A low-complexity FDE-NP that jointly suppresses the ISI and the CCI is derived and is shown to be asymptotically optimal in the sense that the average mean-squared error converges to that of the MMSE Fde-NP as the block length tends to infinity.
