Circulantly precoded OFDM

2016 IEEE/CIC International Conference on Communications in China (ICCC), 2016
Intercarrier interference (ICI) caused by time variance of wireless channels is one of the critical issues faced in orthogonal frequency division multiplexing (OFDM). Conventionally, correlative precoder has been proposed and widely considered to be effective in ICI self-cancellation. However, correlatively precoded OFDM waveforms entail increased peak-

A Linear Precoding Scheme for Downlink Multiuser MIMO Precoding Systems

IEEE Communications Letters, 2011
In this letter, we propose a low complexity linear precoding scheme for downlink multiuser MIMO precoding systems where there is no limit on the number of multiple antennas employed at both the base station and the users. In the proposed algorithm, we can achieve the precoder in two steps.

Trellis precoding: combined coding, precoding and shaping for intersymbol interference channels

IEEE Transactions on Information Theory, 1992
Summary: On a linear Gaussian channel with intersymbol interference (ISI), trellis precoding is a method that achieves the equalization performance of Tomlinson-Harashima (TH) precoding, the coding gain of any known lattice- type coset code, and a considerable shaping gain.
