Pulse Position Amplitude Modulation for Time-Hopping Multiple-Access UWB Communications

Hong-Xin Zhang, Wei Li, T. Aaron Gulliver

Abstract

In this letter, we propose a new modulation scheme called pulse position amplitude modulation (PPAM) for ultra-wideband (UWB) communication systems. PPAM combines pulse position modulation and pulse amplitude modulation to provide good system performance and low computational complexity. The channel capacity of PPAM is determined for a time-hopping multiple-access UWB communication system. The error probability and performance bounds are derived for a multiuser environment.
