In this paper, two novel techniques are proposed to reduce the average optical power in wireless optical multiplesubcarrier modulated (MSM) systems, namely in-band trellis coding a...
Abstract—We describe two classes of simple, effective techniques for reducing the average optical power requirement in intensity-modulated optical systems using multiple BPSK or ...
—Modulation techniques have attracted increasing attention in optical wireless communications. Basic schemes such as on off keying (OOK), pulse amplitude modulation (PAM) and pul...

— In this paper, power efficient signaling over indoor diffuse wireless optical channels is considered. Present-day laser diodes have pulse rates many times higher than the band...
In this paper we investigate the channel capacity of intensity modulated direct detection (IM/DD) wireless optical communication systems for an AWGN channel with a limit on the ave...
