On the capacity of indoor optical wireless communications
IEEE Communications Letters, 2006In this letter, the capacity of an optical wireless communications system in an indoor environment is investigated. We consider various modulation schemes, e.g. pulse-position modulation (L-PPM), differential pulse-position modulation (L-DPPM) and differential amplitude pulse-position modulation (AtimesL-DAPPM).

Optical wireless MIMO communications (OMIMO)
IEEE Global Telecommunications Conference, 2004. GLOBECOM '04., 2005We propose optical wireless multiple-input multiple-output (OMIMO) communications to achieve high speed transmission with a compact transmitter and receiver. In OMIMO, by using zero forcing (ZF), we can eliminate the other signal interferences transmitted from other optical transmit antennas.
