1. DEVELOPMENT OF A MODIFIED ARTIFICIAL FISH SWARM ALGORITHM PARTIAL TRANSMIT SEQUENCE TECHNIQUE FOR PEAK TO AVERAGE POWER RATIO REDUCTION IN ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING
ABSTRACT
Orthogonal Frequency Division Multiplexing (OFDM) is a multi-carrier frequency multiplexing scheme used in broadband wireless communication systems and has advantages such as high spectral efficiency, simple channel equalization and flexibility.One of its major challenges is th...
2. A STUDY ON THE EFFECT OF RAMAN PUMP ON SIGNAL TRANSMISSION OVER FIBER OPTICS CABLE
ABSTRACT
Signal fading and attenuation are key issues in optical transmission over long distances (usually >100km). For example, a transmission link with a length of more than 100 kilometers on fiber optic cable will experience significant packet loss, detectable dropouts, and fluctu...
