Abstract
A discrete wavelet multitone (DWMT) system for communications over hybrid fiber coax (HFC) networks is described. DWMT is a high performance multicarrier modulation technique that provides robust, efficient communications in the presence of the types of channel impairments encountered on the HFC plant. This multicarrier technique, based on a wavelet transform, provides spectral efficiency and achieves significant advantages in the presence of narrowband interference to meet the challenges of providing telecommunication services on HFC networks.Keywords
