A comparative study of the statistical performance of the MUSIC and minimum variance distortionless response (MVDR) direction of arrival (DOA) estimators is presented. Their relative performance due to given modeling errors is studied. In particular, we study the sensitivity of the estimators to modeling errors in the signal and noise structures.
OBJECTIVES (1) To describe the characteristics of sledding injuries presenting to a pediatric emergency department and (2) To describe the sledding environment that leads to childhood sledding injuries. SETTING A pediatric hospital emergency department in Ottawa, Canada and identified sledding sites in the region. METHODS All patients less than 18 years(More)
An analytical tool to help in selecting the number of electrodes required for recording electroencephalogram (EEG) signals is presented. The main assumption made is that the scalp can be modeled as a hemispherical surface. The number of sensors required to sample a surface is derived by using a mean square error (MSE) measure to approximate the continuous(More)
