出典: Pulse-position modulation 『フリー百科事典 ウィキペディア(Wikipedia)』 最終更新 4 April 2018, at 01:28 UTC、URL: https://en.wikipedia.org/ Pulse-position modulation (PPM) is a form of signal modulation in which M message bits are encoded by transmitting a single pulse in one of 2^M possible required time shifts. This is repeated every T seconds, such that the transmitted bit rate is M/T bits per second. It is primarily useful for optical communications systems, where tends to be little or no multipath interference... |
