ABSTRACT
Notice Board is primary thing in any institution / organization or public
utility places like bus stations, railway stations and parks. But sticking various
notices day-to-day is a difficult process. A separate person is required to take
care of this ....etc

Smart Transmitters And Receivers For Under Water Communication
Underwater Free space optical communication promising alternative for Short range links. Considered to be point to point. New optical front end proposed the concept of smart transmitters and receivers. Smart Receivers is capable of detecting angle of arrival of signals. Smart transmitters electronically steers output beam towards particular direction. Estimates water quality from back scattered light.

Advantages are non mechanical pointing and tracking on a moving underwater veh ....etc

smart transmitters and receivers for under water communicationppt

Abstract

The number of unmanned vehicles and devices deployed underwater is increasing. New communication systems and networking protocols are required to handle this growth. Underwater free-space optical communication is poised to augment acoustic communication underwater, especially for short-range, mobile, multi-user environments in future underwater systems. Existing systems are typically point-to-point links with strict pointing and tracking requirements. In this paper we ....etc

Moments and Channel Capacity of Single and
Dual-Branch Receivers Over Weibull Fading Channels



ABSTRACT

Diversity combining receivers is the well-known technique used to combat fad-
ing and improve system performance. There are several diversity reception methods
employed in digital communication receivers including maximal-ratio combining, se-
lection combining and switched diversity. Among the combining methods, switched
diversity offers one of the least complexity solution for fading mitigation and ....etc

Free space optical communications is a line-of-sight (LOS) technology that transmits a modulated beam of visible or infrared light through the atmosphere for broadband communications. In a manner similar to fiber optical communications, free space optics uses a light emitting diode (LED) or laser (light amplification by stimulated emission of radiation) point source for data transmission. However, in free space optics, an energy beam is collimated and transmitted through space rather than being guided through an optical cable. These beams of li ....etc
