... fiber to transmit data from one location to another. The optical fiber is capable of transmitting signals modulated into optical signals (Jeff, 2005). Fiber optics is made up of glass or plastic dielectric material. It consists of central part called core which has a higher refractive index and cladding of lower refractive index (John, 2009). The Fig. 1 below shows the diagram of light signals passing through optical fibers. Optical fiber cable is a guiding medium for light signal to transmit data from one point to another. Light wave is transmitted through the optical fiber by a principle called total internal reflection. The optical fiber contains a central part called core and ...

The objective of this project is to study and construct a motorized flying machine, namely Verticop. Like a bi-copter, it can fly with two blades of propeller. The flying vehicle is capable of flying with thrust force produced by its two propellers. The whole system of this flying vehicle is controlled by a wireless communication system using radio...
Recently, ambient backscatter attracts much attention since it can utilize ambient radio frequency signals to enable battery-free devices to communicate with others. Most existing studies about ambient backscatter assume that the reader is equipped with one receiving antenna. In practice, the reader can utilize multiple antennas to overcome channel...
In this paper, the performance of indoor Terahertz (THz) communication systems with one-bit digital-to-analog converters (DACs) is investigated. Array-of-subarrays architecture is assumed for the antennas at the access points, where each RF chain uniquely activates a disjoint subset of antennas, each of which is connected to an exclusive phase shif...
