Abstract :
Combining L-level pulse-position modulation (LPPM) and L-level pulse-width modulation (L-PWM), this paper describes a new hybrid modulation scheme, L-level Pulse-Position-Pulse-Width Modulation (PPMPWM), which has a relatively low bit error rate, and improved power and bandwidth efficiencies compared to PPM. The properties of the PPMPWM scheme are investigated thoroughly through simulation to show that the scheme is effective in these respects.
