| Abstract | ||
| Adaptive filtering technique has been applied for enhancing and detecting ultrasonic echo signals that are corrupted with noise signals and un-desirable signals. This paper is concerned with enhancing the reflected ultrasonic echoes that are combined with the environmental noise. The adaptive filter is augmented to match the transmission path of the ultrasonic signals and generates a good estimate of the cleaned reflected signal based on minimizing a mean square error criterion. The weight coefficients are updated using the well known LMS adaptation algorithm. The proposed scheme is evaluated by computer simulations. | ||
