Terrestrial or Handheld Digital Video Broadcasting (DVB-T/H) and Terrestrial Digital Multimedia Broadcasting (T-DMB) are two popular broadcasting standards that enable digital television transmissions to handheld receivers. This paper presents a comprehensive performance comparison between the physical layers of DVB-T/H and T-DMB when employed for mobile(More)
A slow-release gonadotropin-releasing hormone (Gn-RH) analogue was administered to 30 males suffering from chronic cluster headache (CH) in a placebo-controlled study with the aim of enhancing neurotransmission in the pain-suppressing systems of the hypothalamus through a feedback action involving neuroendocrine functions too. A significant improvement in(More)
Lisuride is an ergot derivative which acts on serotonin and dopamine receptors at both peripheral and central levels. According to the central theory of headache, lisuride is an active prophylactic drug in adult headache sufferers. Because of its activity on dopamine receptors, a hypotensive action has been observed after acute and chronic administration of(More)
A multibeam satellite system can be modelled as a multiple-input multiple-output (MIMO) system with an interbeam interference matrix that is derived from the positions of the users in the different beams. This way it is possible to apply precoding techniques, such as Tomlinson-Harashima precoding (THP), to mitigate the interference. This paper presents an(More)
A double-blind, placebo-controlled study was carried out in 14 migraineous outpatients and 8 control subjects to assess yawning response to 0.25 mg of sublingual apomorphine, a dopamine receptor agonist, by means of an audiovisual technique. Apomorphine induced a significantly higher number of yawns than placebo in both groups of subjects, but the effect(More)
This paper analyzes the quality of service (QoS) of scheduling algorithms for heterogeneous users in multiuser (MU) wireless systems that take advantage from a crosslayer design with both adaptive modulation and coding (AMC) and automatic repeat request (ARQ). By developing a general theoretical framework based on a finite-state Markov chain, we(More)
This paper deals with the analytical evaluation of the average delay, the packet-loss rate (PLR) and the throughput of a multi-user (MU) wireless system that capitalizes on a crosslayer design of adaptive modulation and coding (AMC) with automatic repeat request (ARQ). To this end, we propose a heuristic scheduling policy, which has the nice properties to(More)
This paper develops a novel simulation model to characterize the bit error rate (BER) performance of coded orthogonal frequency-division modulation (OFDM) systems affected by Doppler spread. This simulation model, which acts directly in the frequency domain, greatly enhances the simulation efficiency, while maintaining a very good accuracy. By this model,(More)
This paper proposes a novel simulation model to characterize the bit-error rate (BER) performance of coded orthogonal frequency-division multiplexing (OFDM) systems that are affected by the Doppler spread. The proposed equivalent frequency-domain OFDM model (EFDOM) avoids the exact generation of the time-varying channel by introducing several parameters(More)
