摘要：
A new scheme called differential pulse position width modulation (DPPM+PWM) in wireless optical communication is discussed. Compared to pulse position modulation (PPM), it does not need symbol synchronization when receiving signals. And it effectively solves the problem of the narrow transmitting pulse width in both differential pulse position modulation (DPPM) and PPM. The symbol structure, the power efficiency, bandwidth efficiency and error performance are analyzed and compared with OOK, PPM, DPPM and PWM. Basing on the given model, the stimulation results show that DPPM+PWM achieves greater ability to bandwidth efficiency and simplifies the receiver. Those improve DPPM+PWM a quite suitable scheme in the wireless optical communication system.
