A synopsis of modulation techniques for wireless infrared communication (original) (raw)

This paper presents a comprehensive overview of modulation techniques applicable to wireless infrared communication systems. It discusses essential metrics such as power efficiency, bandwidth efficiency, and implementation simplicity that influence the selection of modulation schemes. Techniques such as On-Off Keying (OOK), Pulse Position Modulation (PPM), Differential Pulse Position Modulation (DPPM), and others are analyzed, highlighting their respective strengths and applications in both indoor optical wireless settings and broader optical communication contexts.
