Implementation of a basic ADSL System using the DSP kit TMS320C6748

In this paper the implementation of a multi-carrier ADSL digital communication system in a TMS320C6748 DSP Development kit (LCDK) digital signal processor (DSP) is presented. QAM modulation / demodulation schemes, symbol timing and an equalization scheme are implemented. The information sent through the system is processed using cyclic redundancy check blocks, Scrambler and Reed-Solomon encoding. The operation of the system is verified experimentally by designating eight low frequency carriers and using the audio CODEC available in the DSP kit.
