Wireless communications are subject to three major constraints: (i) a complex and unpredictable fading channel, (ii) a scarce radio spectrum, and (iii) limitations on the power and the size of handheld terminals. New technologies have been introduced and evolved based on these constraints. Among all...

The main objective of this paper is to design a novel threshold voltage detector circuit using carbon nanotube field effect transistor (CNTFET). This circuit is simulated in HSPICE by using HSPICE model of CNTFET. The uniqueness of this proposed circuit is that the threshold voltage of each CNTFET d...

Worldwide Interoperability for Microwave Access (WiMax), standardized asIEEE 802.16d is a popular technology for broadband wireless communication system. Orthogonal Frequency Division Multiplexing (OFDM) is the core of this technology.OFDMreduces Inter-symbol Interference (ISI) and hence improves sy...

In this paper, through the basic components of fiber optic communication a novel transmission system called OCDMA (Optical Code Division Multiple Access) based PON with centralized light wave is demonstrated. Here we experimentally investigated the transmission performance of a modulation based on a...
