Abstract: It has been shown that Discrete Multi-Tone (DMT) modulation is an attractive technique for copper wire access technology ( Asymmetric and Very-high-rate Digital Subscriber Line). Discrete Wavelet Multi-Tone (DWMT) is a variant high-performance transmission technique, which is based on the application of wavelet filter bank. However, it was shown in the work that complex wavelet system is very attractive for DWMT. It is usually implemented using parallel filter bank, which have strict design constraints. Instead, a new design method, based on wavelet packet modulation, was proposed. The performances of DWMT system and the standard DMT system were examined in ADSL and VDSL environments.
