PWM-based PPM format for dimming control in visible light communication system [PDF]
We report simulation results of pulse width modulation (PWM)-based pulse position modulation (PPM) signal format for visible light communication systems. For simultaneous operation of data transmission and dimming control, PPM data format is added to PWM

Novel Asymmetrical Pulse Width Modulation Method
The paper proposes new asymmetrical PWM that can be used for operation of multilevel inverters. The working and construction principle of this PWM is demonstrated on 13-level PWM signal that is applied to nine-level inverter and operates it as 13-level ...
