متن کاملSignal processor implementation of DMT based VDSL modems
The Discrete Multi Tone (DMT) modulation is considered a viable technique for high-speed digital transmission over subscriber loop. It was selected as the standard for ADSL modems and it is also a strong candidate in the VDSL area. This paper investigates a programmable solution for the DMT based VDSL modems using Texas Instrument processor family TMS320C62xx. A structure for both transmitter a...
متن کاملSpeech Enhancement by Modified Convex Combination of Fractional Adaptive Filtering
This paper presents new adaptive filtering techniques used in speech enhancement system. Adaptive filtering schemes are subjected to different trade-offs regarding their steady-state misadjustment, speed of convergence, and tracking performance. Fractional Least-Mean-Square (FLMS) is a new adaptive algorithm which has better performance than the conventional LMS algorithm. Normalization of LMS ...

The demands currently placed on medium data rate digital transmission services are for increased spectral eeciency and this factor leads to the development of innovative high speed modem archi-tectures. This paper discusses various aspects of the modem development currently being under-taken by the Institute for Telecommunications Research (ITR) at the University of South Australia (USA) in col...
متن کاملGuest editorial twisted pair transmission-ever increasing performances on ancient telephone wires
Digital subscriber line (DSL) technology for high-speed data transmission over the local-loop telephone twisted pairs was advanced in the labs of several research institutions during the late 1980’s and early 1990’s. Researchers began to develop and experiment with new transmission ideas and to realize high-speed modems in prototype form. As technology matured and standards evolved, these modem...
