—In visible light communications (VLC), the transmitted signal is non-negative and real valued, and these characteristics constrain the signal space and provide new challenges for waveform design in a multiuser system. In Light Fidelity (Li-Fi), a VLC technology, and similar to radio frequency (RF) systems, precoder designs can be used to serve multiple(More)
In this paper, the performance of coded OFDM transmission over multiple antennas is explored when joint transmit and receive antenna selection is employed. The channel is assumed as Rayleigh frequency selective fading channel and only receiver is assumed to have perfect channel state information (CSI). The performance of MIMO OFDM system using pragmatic(More)
