  Pseudo-rapidity distributions of high multiplicity JACEE events ( Ca-C,
Si-AgBr and G27) and Texas Lone Star (TLS) event are analysed by the wavelet
transform method. Using the Daubechies' waveltes, $D_4, D_6, D_8,$ and $ D_{10}
$, wavelet spectra of those events are calculated. Two JACEE events are
compared with the simulation calculations. We discuss how to distinguish
prominent peak from apparent peaks. The wavelet spectrum of Ca-C event seems to
resemble that simulated with the Poisson random number distributions. The
wavelet spectrum of TLS event shows an oscillatory behavior. It is found that
the wavelet spectra of JACEE G27 event are different from those of Arizona
group.
