Simulation of a CDMA System Based on Optical Orthogonal Codes (Electronics Project)
ABSTRACT
To take advantage of the high speed in an optic fiber, one of the basic concept in fiber optic communication is to allow several users to simultaneously transmit data over the channel. One technique that provides multiple access is it fiber optic-code Continue reading
Novel Application of Diffractive Optical Elements in Optical Systems
Dammann proposed the special type of diffraction grating which is periodic in nature together with binary phase for achieving a high splitting ratio. Later on, researchers proposed different kinds of methods for improving the performances. Dammann Gratings can be used in many areas, and in this project, we aim to Continue reading
