Iterative joint channel and data estimation for rank-deficient MIMO-OFDM

, 2007
In this paper we propose a turbo-detected multi-antenna-multi-carrier receiver scheme. Following the philosophy of the turbo processing, our turbo MIMO-OFDM receiver comprises a succession of detection modules, namely the channel estimator, the space ...

Adaptive Unipolar MIMO-OFDM for Visible Light Communications

2019 European Conference on Networks and Communications (EuCNC), 2019
Unipolar orthogonal frequency division multiplexing (U-OFDM) appears as an attractive optical OFDM solution for emerging visible light communication (VLC) systems. This paper proposes spectral efficiency improvement for U-OFDM systems by applying adaptive transmission over realistic VLC links.
