Summary
This study examines wavelength division multiplexing based radio over free space optics (WDM-RoFSO) systems for 5G applications. A dual-channel approach significantly enhances link range across various weather conditions.
Area of Science:
- Optical Communications
- Wireless Technologies
- 5G Networks
Background:
- Radio over Free Space Optics (RoFSO) systems offer high bandwidth potential.
- Wavelength Division Multiplexing (WDM) is crucial for increasing RoFSO capacity.
- 5G networks demand robust and high-capacity wireless backhaul solutions.
Purpose of the Study:
- To investigate the performance of a WDM-RoFSO communication system.

- To assess the impact of a dual-channel technique on system enhancement.
Main Methods:
- Simulation of a WDM-RoFSO system using OptiSystem 0.7 software.
- Modeling four distinct weather conditions: clear, haze, rain, and fog, with associated attenuation.
- Implementation of a dual-channel technique for performance improvement.
Main Results:
- The WDM-RoFSO system was tested with a 30 GHz radio frequency and 160 Gbps bit rate.
- Attenuation losses varied from 0.2 dB/km (clear) to 8 dB/km (fog).
- The dual-channel technique improved link range by 46.1% (clear), 35% (haze), 29.4% (rain), and 25.9% (fog).

Numerous practical applications within engineering disciplines, such as telecommunications, necessitate optimizing power delivery to a connected load. This pursuit, however, entails inherent internal losses, which can either equal or exceed the power supplied to the load. The Thevenin equivalent circuit is helpful in finding the maximum power a linear circuit can deliver to a load. It is assumed in this context that the load resistance can be adjusted.

01:23Design Example
367
The innovation of touch-tone telephony revolutionized the telecommunications industry by replacing the traditional rotary dial with a dual-tone multi-frequency (DTMF) signaling system. This system uses a matrix-style keypad with buttons arranged in four rows and three columns, creating 12 distinct signals each assigned to a pair of frequencies. Each button press results in a simultaneous generation of two sinusoidal tones – one from a low-frequency group (697 to 941 Hz) and one from a...

1.0K
A signal x(t) is a set of data or a time function representing a variable of interest. Signals typically convey information about a phenomenon, such as atmospheric temperature, humidity, human voice, television images, a dog's bark, or birdsongs. More generally, a signal can be a function of more than one independent variable. For instance, images depend on horizontal and vertical positions and can be regarded as two-dimensional signals. However, this text will focus on one-dimensional...

470
Enhancement-mode MOSFETs are pivotal components in electronics, distinguished by their capacity to act as highly efficient switches. They are part of the larger family of metal-oxide Semiconductor Field-Effect Transistors (MOSFETs). They are available in two types: p-channel and n-channel, each tailored to specific polarity operations.
In their basic form, enhancement-mode MOSFETs are typically non-conductive when the gate-source voltage (Vgs) is zero. This default 'off' state means no...

01:15Receiver Operating Characteristic Plot
327
A ROC (Receiver Operating Characteristic) plot is a graphical tool used to assess the performance of a binary classification model by illustrating the trade-off between sensitivity (true positive rate) and specificity (false positive rate). By plotting sensitivity against 1 - specificity across various threshold settings, the ROC curve shows how well the model distinguishes between classes, with a curve closer to the top-left corner indicating a more accurate model. The area under the ROC curve...
