About the group
With the internet and multimedia part of everyday life, we need reliable communication at higher data rates without the cost of laying new cables. The digital subscriber line (DSL) and the power lines are already in place, the "no new wires" solution, but they suffer from multipath propagation, crosstalk and heavy noise.
Multirate signal processing and wavelet transforms can cut costs and improve performance on both. Wavelets already help in compression, coding, denoising, channel modelling and transceiver design, and multicarrier modulation based on the wavelet transform is a promising alternative to the established OFDM and DMT that gives designers the freedom to tailor a system to its channel.
