Abstract :
A method of de-noising seismic signals based on Gabor transform has been proposed as a preprocessing procedure for real-time signals. The proposed method of preprocessing helps in removal of noise when the signal is contaminated by noise. The application of Gabor transform in de-noising has been validated through the simulation results followed by the experimental data. The efficiency of removing the noise by the proposed method has been compared with wavelet analysis. The experimental results prove the efficiency of the proposed de-noising method.
