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.

Full duplex radio transceiver with remote radar detection

TL;DR: In this paper, a radar detector is used with a radio link, the radio link characterized by high duty factor operation of a radio transmitter, and the results of the radar detection are communicated to the transmitter in a way that impacts the transmitter's use of the sensed channel.

Low complexity frequency domain decision feedback turbo equalization with optimized symbol mapping

TL;DR: Simulation results show that the proposed algorithm has comparable performance with the time variant one with frequency domain equalization, and outperforms the algorithm with its equalizer operating in the time domain.

Joint frequency-domain equalization & spectrum combining for transmit filtered single-carrier transmission without CP insertion

Analysis and Simulation of a Digital Mobile Channel Using Orthogonal Frequency Division Multiplexing

TL;DR: The analysis and simulation of a technique for combating the effects of multipath propagation and cochannel interference on a narrow-band digital mobile channel using the discrete Fourier transform to orthogonally frequency multiplex many narrow subchannels, each signaling at a very low rate, into one high-rate channel is discussed.
