ABSTRACT:
The characteristic property of white Gaussian noise (WGN) is derived in
S-transformation domain. The results show that the distribution of normalized
S-spectrum of WGN follows X2distribution with two degrees of freedom. The
conclusion has been confirmed through both theoretical derivations and
numerical simulations. Combined with different criteria, an effective signal
detection in S-transformation can be realized.
