channel estimation for mimo-ofdm systems
تخمین دقیق مشخصات کانال در سیستم های مخابراتی یک امر مهم محسوب می گردد. این امر به ویژه در کانال های بیسیم با خاصیت فرکانس گزینی و زمان گزینی شدید، چالش بزرگی است. مقالات متعدد پر از روش های مبتکرانه ای برای طراحی و آنالیز الگوریتم های تخمین کانال است که بیشتر آنها از روش های خاصی استفاده می کنند که یا دارای عملکرد خوب با پیچیدگی محاسباتی بالا هستند و یا با عملکرد نه چندان خوب پیچیدگی پایینی...
Geometric determinants of electrocardiographic left ventricular hypertrophy.
Experimental studies have suggested that electrocardiographic recognition of left ventricular hypertrophy depends on geometric relationships involving wall thickness and chamber size. To determine the clinical significance of these observations, we studied the effects of echocardiographic LV mass (LVM), posterior wall thickness (PWT), interventricular septal thickness (IVST) and internal dimens...
متن کاملPrognostic value of electrocardiographic criteria for left ventricular hypertrophy.
BACKGROUND Many electrocardiographic (ECG) criteria for left ventricular hypertrophy (LVH) exist, but few studies have compared their relative prognostic value for predicting cardiovascular (CV) mortality. METHODS We analyzed the first ECG on 46950 consecutive veterans. We targeted male outpatients with a body mass index > 20 to avoid confounding by complicating catabolic illnesses and furthe...
متن کاملAn analysis of electrocardiographic criteria for determining left ventricular hypertrophy.
OBJECTIVE To determine the most sensitive criterion for the detection of left ventricular hypertrophy according to echocardiographically defined left ventricular mass. METHODS The Sokolow-Lyon voltage, Sokolow-Lyon-Rappaport, Cornell voltage duration product, White-Bock, and Romhilt-Estes point scoring criteria were compared with left ventricular mass index, corrected for body surface, obtain...
متن کاملEchocardiographic Evaluation of left Ventricular Function and Geometry in Pediatric Patients with Kidney Transplantation
Extended abstract Echocardiographic Evaluation of Left Ventricular Function and Geometry in Pediatric Patients with Kidney Transplantation Cardiovascular disease (CVD) is an important, leading cause of mortality and morbidity in patients with chronic kidney disease (CKD) as well as in renal transplant recipients. Cardiovascular complications become more important in children because of the i...
