In this paper, an unmanned aerial vehicle (UAV) assisted cooperative communication system is studied, wherein a source transmits information to the destination through an energy harvesting decode-and-forward UAV. It is assumed that the UAV can freely move in between the source-destination pair to set up line of sight communications with the both nodes. Since the battery of the UAV may be limite...

Electrical power quality signal generator, capable of reproducing power quality disturbances in accordance with European quality standard EN50160, is presented in this paper. Signal generator is divided in two parts: LabVIEW based virtual instrumentation software for defining the disturbance parameters and hardware electronics for signal generation (data acquisition card and power amplifier). T...

The high Peak to Average Power Ratio (PAPR) of Orthogonal Frequency Division Multiplexing (OFDM) and MIMO-OFDM systems reduces the system efficiency. In this paper, an extension of Tone Reservation (TR) method is introduced for PAPR reduction in Space Frequency Block Coded OFDM (SFBC-OFDM) systems. The proposed algorithm is based on a time domain kernel which is added to the signal of the anten...

In this paper, a recurrent fuzzy-neural network (RFNN) controller with neural network identifier in direct control model is designed to control the speed and exhaust temperature of the gas turbine in a combined cycle power plant. Since the turbine operation in combined cycle unit is considered, speed and exhaust temperature of the gas turbine should be simultaneously controlled by fuel command ...

length, its inductance and fringing capacitance are below 1 nano-henry (nH) and 1 pico-farad (pF), respectively, and it leads only 14 pico-second (ps) time delay [1]. These values are not serious problems of signal integrity (SI). However, when the power/ground plane is considered as a return current path of the through-hole signal via, the electrical performance of the through-hole signal via ...

The development of FPGA-based digital signal processing devices has been gaining attention. Researchers seek to reduce power consumption and enhance signal processing quality in these devices with given resources and spatial limits. Hence, there is a need to investigate both the capability and the power consumption associated with the various digital filtering schemes commonly used in FPGA-base...

A Mobile computer changes its location from time to time. Wireless communication protocols, e.g. IEEE802.11 and HIPERLAN, are widely available in mobile ad-hoc networks. By controlling signal transmission power in a mobile computer, transmission range of the signal is changed. By increasing the signal transmission power, the number of hops for transmitting a message between two mobile computers...

Recently, several power estimation techniques have been proposed. Some of them can be used to accurately estimate power dissipation provided that the exact signal probability probability of a signal being logic ONE) and signal activity (probability of signal switching) of primary inputs are known. In general, very accurate specification of primary input signal probability and activity may not b...
