At the reception of wireless communications the wavelet packet-division multiplexing (WPDM) has shown susceptibility to multipath fading. Inspired by WPDM, this paper proposes a new scheme of multiplexing, which has been called “Dynamic Wavelet Packet-Division Multiplexing (DWPDM)”, that allow adapt to the channel conditions and improve their performance both in time-variant as time-invariant channels. The proposed scheme also allow increase the quality of service and improve the security of transmission of binary message thanks to the random variation in the time of the carries or wavelet packet functions. The scheme were evaluated by simulation in three communication scenarios: AWGN channel, selective fading channel and slowly-varying notch channel, showing improvement compared with WPDM, Branch-Hopped WPDM and WOFDM.
