The digital subscribers line (DSL) technology that make use of existing telephone lines in a high-bandwidths data, such as multimedia and videos files transmit the service to they subscribers. It provides digital subscriber line exclusive access point-to-point on the public network. DSL connection is usually between the central office of the Network Service Provider (NSP) and the location of the client. The main objectives of this work are to design, simulate and implement the Discrete Multitone (DMT) demodulator for ADSL for a real transmission based on Software Defined a Radio (SDR), using F...
The digital subscribers line (DSL) technology that make use of existing telephone lines in a high-bandwidths data, such as multimedia and videos files transmit the service to they subscribers. It provides digital subscriber line exclusive access point-to-point on the public network. DSL connection is usually between the central office of the Network Service Provider (NSP) and the location of the client. The main objectives of this work are to design, simulate and implement the Discrete Multitone (DMT) demodulator for ADSL for a real transmission based on Software Defined a Radio (SDR), using FPGAs. Experimental results of the proposed system show the coincidence between transmitted and received data with simulation results which are obtained from MATLAB and ModelSim results with small distortion because of the practical environment, for data rate 10 Kb/s, 100 Kb/s, 500 Kb/s and 1Mb/s.
