In this paper, simulation and implementation of
Asymmetric Digital Subscriber Line (ADSL) modem is presented
which can be applied to different telephone networks. The ADSL
modem is modeled and simulated under the MATLAB version 7.3
(R2006b) environments by which the simulation is achieved for
both the downstream and upstream directions of the modem. The
ADSL modem with a transmission throughput between 640 kbps
and 6 Mbps operating over most of existing telephone subscriber
loops has been implemented on TI TMS320C6713 DSP for
consumer multimedia applications. Except the Analog Front End,
all the basic building blocks of the ADSL modem functionalities
are implemented with DSP platform. We use Real-Time Data
Exchange (RTDX) as a way to debug and test our DSP designs.
