Abstract :In this paper, the problem of signal-to-noise ratio insert ignore into journalissuearticles values(SNR); estimation of noisy transient signals is considered. The SNR estimation is performed based on the average energy of the transient and noise signals. The performance of the SNR estimator is evaluated in terms of normalized mean square error and normalized bias. It is shown by simulations that the SNR estimation method exhibits good estimation performance for the SNRs encountered in many practical applications. Besides, the effect of the estimation of the transient starting point on the performance of the SNR estimation is investigated
Keywords : SNR estimation, transient signal detection, normalized bias, normalized mean square error
