En fordel ved WOFDM er, at guard-intervallet bliver overflødigt med de rette valgte ortogonale Wavelet-funktioner, da disse både er ortogonale med Wavelets fra samme familie - i samme tidsinterval - og for ortogonal tidsforskudte tider.<ref name="WU101"/><ref>[http://cmpicsu.utt.ro/docs/cercetare/articole/Olt07.pdf Wavelet OFDM Performance in Flat Fading Channels.

The fading envelope is distributed according to a Rayleigh probability density function....Besides its incontestable advantages, OFDM presents some well known drawbacks as: diminished spectral efficiency because of the cyclic prefix (CP) overhead, slow decay of the out-of-band side-lobes, high sensitivity to time and frequency synchronization, increased peak-to- average-power ratio [1,2]....The authors in [5] have shown that wavelet-based OFDM (WOFDM) has better spectral efficiency, is simpler and at least as rapid as OFDM in practical implementations......"</ref><ref>{{Cite web |url=http://ndgohar.seecs.nust.edu.pk/pages/cse/downloads/Sweden%20Tour-Presentations/Asma/Performance%20Analysis%20of%20Wavelet%20OFDM%20%28WOFDM%29.pdf |title=Performance Analysis of Wavelet OFDM (WOFDM) By Asma Latif, Dr. N.D.
