Spatial modulation aided zero-padded single carrier transmission for dispersive channels [PDF]

, 2013
In this paper, we consider spatial modulation (SM) operating in a frequency-selective single-carrier (SC) communication scenario and propose zero-padding instead of the cyclic-prefix considered in the existing literature.

Equivalent Space Vector Output of Diode Clamped Multilevel Inverters Through Modulation Wave Decomposition Under Carrier-Based PWM Strategy

IEEE Access, 2020
The carrier-based PWM method (CBPWM) and the space vector PWM method (SVPWM) are two main modulation methods for diode clamped multilevel converters, and there is a certain relationship between these two modulation strategies.
