This paper investigates the modulation schemes in visible light communication (VLC)
system. On-off keying (OOK), and pulse position modulation (PPM) one used widely in …

In this paper, we have characterized the performance of an intensity modulation/direct
detection (IM/DD), free space optical (FSO) communication system in terms of average …

The LED (Light emitting diode) based lighting systems are gaining popularity for its dual use
ie for energy efficient lighting systems as well as for indoor optical wireless communication …

Future space missions will be driven by factors such as the need for reduced cost of
spacecraft without diminished performance, new services, and capabilities including …

Предложен подход, который позволяет снизить негативное влияние многолучевого
распространения сигнала в беспроводном канале связи, проявляющееся в виде …

This paper presents the combination of pulse position modulation (PPM) and pulsed fiber
laser in order to improve the problem that the pulsed fiber laser with high power but low …

An approach to reduce the negative impact of multipath signal propagation (interpulse
interference) in a wireless communication channel has been proposed. Pulse-interval …

In this paper, an improved version of existing modulation schemes is investigated by
inserting Hadamard codes (HC) at the peak slot of each symbol for the Visible Light …
