Transmitter Preprocessing Aided Spatial Modulation for Multiple-Input Multiple-Output Systems

, 2011
This paper proposes and studies a transmitter preprocessing aided spatial modulation (PSM) scheme, which conveys information jointly by a conventional amplitude-phase modulation (APM) and a preprocessing aided space shift keying (pre-SSK) modulation.

Modulation of Current Source Inverter [PDF]

Journal of Intelligent Procedures in Electrical Technology, 2011
Direct torque control with Current Source Inverter (CSI) instead of voltage source inverter is so appropriate because of determining the torque of induction motor with machine current and air gap flux. In addition, Space-Vector Modulation (SVM) is a more
