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.p { text-indent: 0.51cm; margin-bottom: 0.21cm; direction: ltr; letter-spacing: -0.1pt; line-height: 95%; text-align: justify; orphans: 2; widows: 2; background: transparent }p.western { so-language: x-none }p.cjk { so-language: x-none }a:link { color: #0563c1; text-decoration: underline }
