Spatial modulation (SM) is a particularly important form of multiple-input multiple-output (MIMO), which uses both symbols and antenna indices to carry information. In this paper, avoid the high cost circuit complexity SM, we consider hybrid SM system with precoding transmitter architecture, combining digital precoder an analog precoder. such system, carried out secure transmit subarray selecti...

Use of multilevel inverters has become popular in recent years for high-power applications. Various topologies and modulation strategies have been investigated for utility and drive applications in the literature. Trends in power semiconductor technology indicate a tradeoff in the selection of power devices in terms of switching frequency and voltage-sustaining capability. New power converter t...

Power electronic converters are becoming more and more popular for various industrial applications. To overcome the limitation of semiconductors current and voltage ratings in high power applications, series and parallel connection of switches is often considered an effective solution. In addition, stepped waveform in the output of inverter has better harmonic spectrum than 2-level waveform in ...
