In this paper, design, 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. |
