The objective of this work is to detect delay times between two ultrasonic signals, one of them considered as a reference and the other signal as the signal to be evaluated, using the wavelet transform, to indirectly estimate temperature changes. In

Golay codes posses the property that combining the products of the two individual codes of the pair causes the self-induced noise to cancel out. This gives significant improvements in the signal to noise ratio obtained with short codes in signal to n
