In this paper the problem of detecting the equality of signals is studied. It is common practice to check the equality of the known orignal signal and the received signal by parametric methods in the Gaussian case. Several methods based on nonparametric estimators of the signal are described. In this setting, the distribution of the test statistic is difficult to compute or cannot be determined analytically. For this reason, we propose the use of statistical bootstrap algorithms as an alternative approach. A simulation study is conducted to investigate the finite sample properties of the test.
