Journal ArticleDOI
Dual header pulse interval modulation for dispersive indoor optical wireless communication systems
TL;DR: It is shown that for given parameters, DH-PIM requires marginally higher optical power compared with PPM and DPIM, but it supports the same bit rate with much lower bandwidth requirement.
Journal ArticleDOI
Error performance of dual header pulse interval modulation (DH-PIM) in optical wireless communications
TL;DR: It is shown that DH-PIM offers improved error performance compared with OOK and PIM, but is marginally inferior to PPM.
Journal ArticleDOI
Baseline-wander effects on systems employing digital pulse-interval modulation
TL;DR: The error performance of DPIM, as a function of high-pass filter (HPF) cut-on frequency, is compared with the more established techniques of on-off keying using nonreturn-to-zero signalling and pulse-position modulation (PPM), using both numerical analysis and computer simulation.
Proceedings ArticleDOI
Performance of dual header-pulse interval modulation (DH-PIM) for optical wireless communication systems
TL;DR: It is shown that, DH-PIM offers higher bit rate and has a built-in frame synchronization capability and the optimum system performance in terms of optical power and bandwidth requirements is achieved at bit resolution of 5.12.
Journal ArticleDOI
Indoor optical wireless systems employing dual header pulse interval modulation (DH-PIM)
TL;DR: Theoretical and simulation results demonstrate that DH‐PIM offers shorter symbol length, improved transmission rate and bandwidth requirement and a comparable power spectral density profile compared with digital pulse interval modulation (DPIM) and pulse position modulation (PPM) schemes.
