In the ATSC 3.0 PHY layer standard, a transmitter identification (TxID) signal is defined in order to provide the identification of an ATSC 3.0 transmitter. TxID signal can also be used to find the co-channel and adjacent interference signals, to assist accurate location finding calculation, and to obtain the channel estimation for each transmitter, which can help local service (e.g., targeted advertisement)...
Magnetic Resonance Fingerprinting (MRF) is a relatively new approach that provides quantitative MRI using randomized acquisition. Extraction of physical quantitative tissue values is preformed off-line, based on acquisition with varying parameters and a dictionary generated according to the Bloch equations. MRF uses hundreds of radio frequency (RF) excitation pulses for acquisition, and therefore...
To measure the volatility spillover effects between gold market and stock market, a VAR-DCC-BVGARCH model is utilized to analyze the relationship of both. The bivariate GARCH model (BVGARCH), employed to simultaneously capture the conditional volatilities of both assets and the dynamic conditional correlation model, used to estimate their time-varying conditional correlation are combined. Empirical...
We present the design and simulation of temperature compensated Radio-Frequency (RF) Free-Free (FF) beam MEMS resonators that are developed using PolyMUMPS, which is a commercial multi-user process available from MEMSCAP. The proposed devices, which operate at 10MHz and 20MHz, are designed using CoventorWare finite element modeling software. We present a novel and effective temperature compensation...
Dans cet article il est question de calibration automatique de la porteuse résiduelle. La relation entre la porteuse résiduelle et le mélangeur est établie. On décrit le principe de la calibration automatique et le bloc de contrôle numérique qui repose sur un dé;tecteur de puissance basé sur la diode Schottky.
