Challenges in Gbps Wireless Optical Transmission
In this paper, the link budget of Gbps wireless infrared indoor communication is analysed. We particularly focus on the receiver sensitivity and identify the most suitable wavelengths range. We show that an optical receiver operating at 1 Gbps will hardly achieve the shot noise limit, which is determined by the received amount of background light. Regarding the link budget, we present two case ...
متن کاملBlue Laser Diode Enables Underwater Communication at 12.4 Gbps
To enable high-speed underwater wireless optical communication (UWOC) in tap-water and seawater environments over long distances, a 450-nm blue GaN laser diode (LD) directly modulated by pre-leveled 16-quadrature amplitude modulation (QAM) orthogonal frequency division multiplexing (OFDM) data was employed to implement its maximal transmission capacity of up to 10 Gbps. The proposed UWOC in tap...
متن کامل40 Gbps / 100 Gbps Large - Capacity Optical Transmission Equipment
1. Introduction In order to meet the rapidly increasing demand for communications over metro networks and international submarine cable networks, it is essential to secure larger transmission capacity and higher equipment reliability. Indispensable technologies to satisfy these requirements include: design and verification technologies that realize large-capacity transmission of 40 and 100 Gbps...
متن کاملLPS: Laser Positioning System for Underwater Networks
Underwater Sensor Networks (UWSN) have many potential applications, such as ocean exploration, pollution monitoring, public safety and military underwater surveillance [1]. In all of these applications, localization plays an important rule since detected events must be tagged with position information. Moreover, position may also be required for geographical routing. GPS is not available in und...
متن کاملCompressive sensing underwater laser serial imaging system
Compressive sensing (CS) theory has drawn great interest in recent years and has led to new image acquisition techniques in many different fields. This research investigates a CS based active underwater laser serial imaging system, which employs a Spatial Light Modulator (SLM) at the source. A multi-scale polarity flipping measurement matrix and a model-assisted image reconstruction concept are...
