Abstract
The performances of dual-header pulse interval modulation(DH-PIM) and digital pulse interval modulation(DPIM) are analyzed for the high packet error rate and low information transmission rate of optical wireless communication modulations presently.After discussing their symbol structures,their packet error rates and information transmission rates are compared based on the given model.The simulation results show that DH-PIM with higher information transmission rate is fit for real-time transmission systems,while DPIM is fit for lower power or higher reliability systems for it's lower average power and packet error rate.
