Sparsity-Aware Nonlinear Equalization With Greedy Algorithms for LED-Based Visible Light Communication Systems

The nonlinearity of light emitting diode (LED) in visible light communication (VLC) systems is considered as one major limiting factor that deteriorates the systems' performance. In this paper, the nonlinear equalization in VLC systems is deemed to be a sparse recovery problem. Three different...
