This paper proposes D4 FLMS-GSC algorithm interpreted as Daubechies D4 wavelet filter instead of subtractor filter which processes array antenna output. The structure of the proposed D4 FLMS-GSC algorithm has characteristic of reducing the computational requirement one-half compared to the FLMS-GSC algorithm. In addition, we obtain the MSE characteristics and adaptive beampattern of the D4 FLMS...

We develop a theoretical framework for the dissipative propagation of quantized light under conditions of electromagnetically induced transparency in atomic media involving strongly interacting Rydberg states. The theory allows us to determine the peculiar spatiotemporal structure of the output of the recently demonstrated single-photon filter and the recently proposed single-photon subtractor,...

In this paper, an optical half adder is designed using photonic crystals. One of the features its small size. design structure, it has been tried to have a size, shorter delay and high contrast ratio so that can be used in integrated circuits. For sum carry outputs, obtained 15.4 dB 7.4 dB, respectively. addition, proposed structure size 70 µm2. The use simple point defects, caused maximum time...

In this paper, a novel design of an all-optical half-adder (HA) based on two two-ring resonators in two-dimensional square-lattice photonic crystal (PC) structure without nonlinear materials is proposed. The HA comprises AND and XOR gates where each gate composed cross-shaped waveguides 2D PC that are filled with silicon (Si) rods silica (SiO2). analyzed simulated using plane-wave expansion (PW...

This paper proposed an efficient implementation of digital circuit based on the Euclidean Algorithm with modular arithmetic to find Greatest Common Divisor (GCD) of two Binary Numbers given as input to the circuit. Output of the circuit is the GCD of the given inputs. In this paper subtraction-based narrative defined by Euclid is described, the remainder calculation replaced by repeated subtrac...

Quantum-dot cellular automata, is an extremely small size and a powerless nanotechnology. It is the possible alternative to current CMOS technology. Reversible QCA logic is the most important issue at present time to reduce power losses. This paper presents a novel reversible logic gate called the F-Gate. It is simplest in design and a powerful technique to implement reversible logic. A systema...
