Maximal Ratio Combining Detection in OFDM Systems with Virtual Carriers Over V2V Channels.

This paper examines the performance of orthogonal frequency division multiplexing (OFDM) systems for vehicle-to-vehicle (V2V) communication channels. More specifically, a doubly selective channel under high intercarrier interference (ICI) is considered. Current solutions involve complex detection and/or reduced spectral efficiency receivers.

Effects of early use of atenolol or captopril on infarct size and ventricular volume: A double-blind comparison in patients with anterior acute myocardial infarction.

Background: beta-Blockers and ACE inhibitors reduce early mortality when either one is started in the first hours after myocardial infarction (MI). Considering the close correlation between morphological changes and prognosis, we aimed to investigate whether the benefit of both beta-blockers and ACE inhibitors might reside in a similar protective effect on infarct size or ventricular volume.

Methods And Results: In a randomized, double-blind comparison between early treatment with captopril or atenolol in 121 patients with acute anterior MI, both drugs showed a similar reduction in mean blood pressure.

Incidence, clinical characteristics, and prognostic significance of right bundle-branch block in acute myocardial infarction: a study in the thrombolytic era.

Background: Whereas the significance of right bundle-branch block (RBBB) in acute myocardial infarction was extensively studied in the prethrombolytic era, a possible change in the overall incidence and meaning of RBBB as a consequence of thrombolytic therapy is not well known.

Methods And Results: A multicenter, prospective study of 1238 patients consecutively diagnosed with acute myocardial infarction and admitted to three coronary care units was conducted. ECGs during the acute phase and clinical events until discharge and 1-year follow-up were monitored.

[The prognostic significance of complete atrioventricular block in patients with acute inferior myocardial infarct. A study in the era thrombolytics].

Introduction And Objectives: Complete atrioventricular block (CAVB) during inferior acute myocardial infarction (AMI), characterizes a high-risk subgroup of patients. This study was designed to determine the incidence and meaning of CAVB associated with inferior AMI and their peculiarities in relation to thrombolytic therapy.

Methods: Prospective and multicenter, involving 605 patients consecutively admitted with inferior AMI.

[Intracranial hemorrhage following thrombolytic therapy in acute myocardial infarct].

Introduction: Intracranial hemorrhage in acute myocardial infarction, under thrombolytic therapeutic, ranges from 0.3 to 3% in different trials. We carried out a study to stabilised the incidence of this complication in ours patients, as well as to analyze its characteristics and asses the presence the predictive factors.
