Hybrid Shape, Amplitude, and Position Modulation for UWB Communication Systems
نویسندگان
چکیده
In this paper we introduce a novel method for high data rate transmission in ultra-wideband (UWB) communications systems. This is achieved through a new approach based on hybrid techniques between pulse position modulation (PPM), pulse amplitude modulation (PAM) and pulse shape modulation (PSM) using combinations between a minimum possible number of modified hermite polynomial (MHP) functions by recalling their orthogonality property. In this paper we have based our discussion on single path scenario assuming beam forming is taking place to combat multipath propagation. Besides, the impact of time jitter of the proposed modulation technique on the performance of the system is investigated.

Analytical Performance Evaluation of Time-hopping Pulse Position Amplitude Modulation Ir-uwb Systems under Multi User Interference
Trends in modern communication systems place high demands on low power consumption, high speed transmission and anti-interference characteristics. Therefore impulse radio ultra–wideband (IR-UWB) [1] radio systems have recently gained increased popularity. Since IR-UWB symbols are transmitted with short pulses (< 2 ns), in IR-UWB systems, energy has been spread over the frequency bands of up to ...
