The application of a single-pulse position modulation (SPPM) and a new concatenated single-pulse position modulation
(CPPM) for data transmission in optical indoor channels is shown. The numerical analysis of the extended multi-pulse
position modulation (MPPM) and CPPM for information transmission done in aspects of bandwidth, power efficiency
and symbol error probability (SER) has shown the better performance of CPPM and MPPM than SPPM at the cost of
increased bandwidth. The obtained simulation results of SER for modulation schemes are close to theoretical SER
evaluation and have shown the increase of power spectral density (PSD) of MPPM in comparison with SPPM.
