China Telecom Proposal for Unified Modulation Schemes
Explore China Telecom's PHY proposal for Pulse Amplitude and Pulse Position Modulation (PAPM) in IEEE P802.15 Working Group for Wireless Personal Area Networks (WPANs). The proposal includes M-n-PAPM schemes, modulation schemes like OOK, VPPM, and CSK, and the flexibility of defining amplitude and position based on application scenarios. Learn how different combinations of M and n in M-n-PAPM schemes offer various modulation options. Dive into detailed time waveforms and the transition between different schemes for efficient data transmission.

doc.: IEEE 15-16-0229-01-007a March 2016 PAPM(Pulse Amplitude and Pulse Position Modulation) The M-n-PAPM refer to M level amplitude and n-PPM, by select different combination of M and n, the M-n-PAPM scheme can be obtained. When M = 1, the 1-n-PAPM becomes n-PPM, and when n=1, the M-1- PAPM becomes M-PAM Slide 6 China Telecom Submission
