VLC is communications using light that can be seen by the human eye. Dimming control of a light emitting diode is an important component needed to provide energy savings and quality of life. SM-MIMO provides a channel capacity and data rate proportional to the number of antennas in the wireless environment. In this paper, we used an SM scheme among the MIMO schemes of the VLC system. We analyzed communications...
We present a link adaptation strategy for multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) based wireless communications. Our objective is to choose the optimal mode that will maximize energy efficiency or data throughput subject to a given quality of service (QoS) constraint. We formulate the link adaptation problem as a convex optimization problem and expand...
