In this letter, the error performance of an ultra-wideband (UWB) system with a hybrid pulse amplitude and position modulation (PAPM) scheme over indoor lognormal fading channels is analyzed. In the PAPM UWB system, input data is modulated onto both the pulse amplitudes and pulse positions.
FreeTTS is a speech synthesis system written entirely in the Java
programming language. It is based upon Flite, a small, fast, run-time speech
synthesis engine, which in turn is based upon University of Edinburgh s
Festival Speech Synthesis System and Carnegie Mellon University s
FestVox project.
This m file models a DPSK UWB system using a delay in one leg of the mixer, correlation receiver low pass filter combination requiring no template for synching. Various waveforms are displayed throughout the system to allow the user to observe operation of the system.
