SAGE version 7.0 algorithm: application to SAGE II

An Application of SAGE Algorithm for UWB Propagation Channel Estimation

In this paper, a new Ultra Wideband (UWB) channel estimation algorithm, UWB-SAGE (Space Alternating Generalized Expectation Maximization) is proposed. This algorithm is an extension of conventional SAGE algorithm which is often adopted for wideband channel estimation. The algorithm divides the measured data into individual ray paths and estimates the directions of arrival, propagation time, and...

SAGE Algorithm for UWB Channel Parameter Estimation

UWB signals have become popular for ranging and positioning systems. Since such systems require the extraction of location related information from the radio channel, efficient methods are required to obtain the parameters of interest. This paper presents a simple extension to the SAGE algorithm that makes the algorithm suitable for analyzing UWB channels. It is demonstrated that a phased array...

Radio Interferometric Calibration Using The SAGE Algorithm

Radio Interferometry is an essential method for astronomical observations. Self-calibration techniques have increased the quality of the radio astronomical observations (and hence the science) by orders of magnitude. Recently, there is a drive towards sensor arrays built using inexpensive hardware and distributed over a wide area acting as radio interferometers. Calibration of such arrays poses...
