Performance of Multi Pulse Position Amplitude Modulation for TH IR-UWB Communication Systems
The multi pulse position amplitude modulation scheme for time-hopping multiple access impulse radio ultrawideband communication systems has been presented in this paper. Multi pulse position amplitude modulation is a hybrid modulation technique, which combines multi pulse position modulation and pulse amplitude modulation. It is shown that multi pulse position amplitude modulation significantly...
متن کاملAnalytical 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 ...
متن کاملHybrid Shape, Amplitude, and Position Modulation for UWB Communication Systems
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 b...
متن کاملPerformance of Receive Diversity UWB Systems with Pulse Amplitude and Position Modulation
In this paper, we extend ultra-wideband (UWB) single input single output (SISO) systems with a hybrid pulse amplitude and position modulation (PAPM) to single input multiple output (SIMO) systems using receive antenna diversity. The performance of a rake receive diversity combining scheme for UWB SIMO systems with a PAPM is examined in a log-normal multipath fading channel and also compared wit...
متن کاملPerformance analysis of trellis coded multi-pulse pulse position modulation for deep space optical communication systems
The deep space optical communication is unguided optical communication without fiber, but is power and bandwidth limited. Technique used for communication in such a system is usually IM/DD and the choice of modulation is pulse position modulation since it is extremely power efficient, but it results in an exponential increase in required bandwidth. To overcome this limitation, multi-pulse PPM i...
