Stationary Echo Canceling in Velocity Estimation by Time-domain Cross-correlation Stationary Echo Canceling in Velocity Estimation by Time-domain Cross-correlation

Abstract

The application of stationary echo canceling to ultrasonic estimation of blood velocities using time-domain cross-correlation is investigated. Expressions are derived that shows the innuence from the echo canceler on the signals that enter the cross-correlation estimator. It is demonstrated that the ltration results in a velocity dependent degradation of… (More)
