Currently, triple phase-shift (TPS) modulation has attracted more and attention of researchers as an advanced strategy for dual active bridge converter (DAB). Since it three degrees freedom, can realize better performance both in soft switching ranges power efficiency. However, how to choose these freedom optimal efficiency DAB becomes a concern researchers. Generally, there exist two difficult...

A peak to average power ratio (PAPR) reduction method is proposed that exploits the precoding or beamforming mode in WiMAX. The method is applicable to any OFDM/A systems that implements beamforming using dedicated pilots which use the same beamforming antenna weights for both pilots and data. Beamforming performance depends on the relative phase shift between antennas, but is unaffected by a p...

In the present work, Bi2S3 nanostructures have been synthesized with the aid of thioglycollic acid (TGA) a solvent, capping agent, and sulfide source in the presence of ultrasonic method. The as-synthesized products were characterized by X-ray diffraction (XRD), Energy Dispersive X-ray spectroscopy (EDS), scanning electron microscope (SEM), and photoluminescence (PL) spectroscopy. The band gap ...

Out of more than 40 submissions received from experts in the field for this Special Section, and after more than 100 reviews, only eight manuscripts could be accepted to be included in this issue. These eight papers cover various areas related to low-power electronics and design, ranging from circuit and design technology to system level power modeling and optimization. Starting from the lowest...

An all-optical shift register based on Self Electro-Optic Effect Devices is introduced. The switching behavior, system performance and some possible improvements are presented. Calculations show the system bit rate could be up to 790 Mbps with 1 mW clock power. An improved scheme is discussed, which can provide 2 Gbps throughput for 1 mW clock power. Finally we presented an application of this ...

In mobile communications, power is a very important factor and nonlinear amplification of power amplifiers cannot be avoided due to their high power efficiency. This article presents the performance of 2 -shift BPSK modulation scheme used in DS/SS/CDMA wireless communications over multipath Rayleigh fading channel and compares the performance with the performance of conventional BPSK CDMA syste...

We examine how a shift of bargaining power within households operating in a competitive market environment affects equilibrium allocation and welfare. If price effects are sufficiently small, then typically an individual benefits from an increase of bargaining power, necessarily to the detriment of others. If price effects are drastic the welfare of all household members moves in the same direc...
