This paper presents the first DRM+ (Digital Radio Mondiale, Mode E) Single Frequency Network (SFN) in the air. A field trial has been conducted to evaluate the performance in different environments. Due to it’s relatively small bandwidth, flat fading in the overlapping area can become a problem. Different solutions to overcome this problem are evaluated in this paper. Adding different delays to...

The presentation explores diplophonia via numerical simulations of glottal vibrations. The aim of the study is to improve the understanding of glottal wall vibration and area waveform patterns of nonmodal phonation as observed via laryngeal highspeed videos. Diplophonia has been described as the simultaneous perception of two pitches during voicing. A broader definition is the vibration of diff...

We explore the feasibility of Terrestrial Broadcasting in a Single-Frequency Network (SFN) with standard 5G New Radio (5GNR) numerology designed for uni-cast transmission. Instead classical OFDM symbol-by-symbol detector scheme or more complex equalization technique, we Recurrent-Neural-Network (RNN)-based that replaces channel estimation and blocks. The RNN is bidirectional Long Short-Term Mem...

Future wireless communication systems would have to support very high data rates. As this vision is not feasible with the conventional cellular architecture without increasing the density of the base stations, in order to increase the capacity, different transmit diversity schemes have been heavily investigated in the past years. Relaying has been one of those areas investigated and has been pr...

Long Term Evolution (LTE) is the most promised latest step towards the 4th generation (4G) of radio technologies designed to increase the capacity and speed of mobile communications with main target the support of the so-called “Mobile Broadband”. To support Multimedia Broadcast/Multicast Services (MBMS), LTE offers the possibility to transmit Multimedia Broadcast multicast service over a Singl...

In this paper, we investigate the performance of LTE Multicast-Broadcast Single-Frequency Networks (MBSFN). LTE-MBSFN is viewed as one of the most promising candidates for vehicular communications which can enhance reliability of vehicular application traffic. This is achieved due to the possibility to efficiently support message exchange in-between vehicles by multicasting information to sever...

spectral decomposition is a powerful tool for analysis of seismic data. fourier transform determines the frequency contents of a signal. but for analysis of non-stationary signals, 1-d transform to frequency domain is not sufficient. in early years, transforming of seismic traces into time and frequency domain was done via windowed fourier transform, called a short time fourier transform (stft)...
