چکیده

Ultra-wideband (UWB) uses narrow band pulses of nano-seconds to provide high data rate communications .These narrow pulses spread the energy across a wide frequency band that is why it is called ultra-wideband. In this paper, we will discuss the UWB pulse modulation and multiple access modulation schemes using Pulse Position Modulation technique .The simulations are done in MATLAB software.

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...

Pulse Interval Modulation for Ultra-High Speed IR-UWB Communications Systems

This paper analyzes performances of the Pulse Interval Modulation (PIM) scheme for impulse radio ultra-wideband (IR-UWB) communication systems. Due to the PIM anisochronous nature, a tap delay line (TDL) coded division multiple access (CDMA) scheme based on strict optical orthogonal codes (SOOC) is proposed. This scheme is suitable for multiuser high-speed data asynchronous transmission applica...

QPSK Impulse Signal Transmission for Ultra Wide Band Communication Systems in Multipath Channel Environments

In this paper, three new ultra wideband (UWB) communication systems with quadrature-phase shift keying (QPSK) impulse modulation are proposed. First, direct-sequence (DS) multiple-access scheme is applied. The second proposed system is based on time-hopping (TH) multiple-access scheme. The last proposed system applies TH multipleaccess scheme with QPSK impulse modulation and pulse position modu...

Frequency and Time Hopping PPM UWB Multiple Access Communication Scheme

In this paper we propose frequency and time hopping pulse position modulation (FTH-PPM) ultra wideband (UWB) for multiple access communications. We have derived and investigated the bit error probability for the multi-user synchronous transmitter case in multipath channels with Additive White Gaussian Noise (AWGN). Simulation results show that bit error probability performance of FTH-PPM UWB ou...

An enhanced pulse position modulation (PPM) in ultra-wideband (UWB) systems

Simplicity, transmission rate, and bit error rate (BER) performance are three major concerns for ultra-wideband (UWB) systems. The main advantage of existing pulse-position modulation (PPM) schemes is simplicity, but their BER performance is poorer than that of an on-off-keying (OOK) modulation scheme, and their transmission rate is lower than that of an OOK scheme. In this research project, I ...
