We performed a comprehensive investigation that revealed the beneficial features of PDSM, and its pulse shape was proven to be spectrally more efficient than that of a variable pulse position modulation (VPPM) pulse over the entire light intensity range.
The carried out experimental studies confirmed that the used approach to short-distance transmission of timed event data makes it possible to achieve at least 10 picosecond resolution at pulse position modulation using 24 MHz reference sine wave.
A similar yet a simpler approach is proposed to undergo pulse position modulation.
