The characteristics of dual header pulse interval modulation (DH-PIM) in indoor optical wireless systems

In this paper DH-PIM modulation scheme and its properties are discussed. Expressions for, symbol length, transmission capacity, bandwidth requirements, photocurrent, power spectral density and slot and packet error rates are presented. Results obtained for the packet error rate are compared with OOK and PIM. It offers the same performance as PIM but considerably better performance compared with OOK.
