Performance Analysis of Pulse Analog Control Schemes, predominantly Pulse-Width Modulation (PWM) and Pulse-Position Modulation (PPM) for LLC resonant DC/DC converter suitable in portable applications is addressed in this paper.
The modulation schemes that consist of pulse amplitude modulation (PAM), pulse position modulation (PPM), and pulse position amplitude modulation (PPAM) are widely adopted in IR-UWB systems.
The two widely adopted modulation schemes for IR-UWB systems are binary pulse amplitude modulation and binary pulse position modulation.
The popular ED schemes include on-off keying (OOK) and pulse position modulation (PPM) [3].
ED has been applied to on-off keying (OOK) and pulse position modulation (PPM) [5].
In [5, 6], the channel capacity of UWB systems with M-ary pulse position modulation (PPM) is examined, and this is extended to biorthogonal PPM (BPPM) and pulse position amplitude modulation (PPAM) in [7, 8].
Ultra-wideband (UWB) impulse radio (IR) transmits ultra-short pulses at low power spectral density where the information is encoded via pulse-amplitude modulation (PAM) or via pulse-position modulation (PPM).
This chapter discusses encoding and modulation schemes, pulse code modulation, pulse amplitude modulation, pulse position modulation, pulse number modulation, pulse width modulation, and pulse density modulation.
Modulation and pulse modes will be disabled in order to maintain uniformity of electrotherapy protocols.
To this purpose, a quite general backscatter modulator architecture has been proposed in [24], allowing for different signaling schemes, such as pulse amplitude modulation (PAM), pulse position modulation (PPM), and ON-OFF keying.
