ADSL Coding Techniques

ADSL has a number of coding techniques:
i) Single Carrier - uses Carrierless Amplitude and Phase Modulation (CAP) - Proprietary
ii) Multiple Carrier - uses Discreet MultiTone Modulation (DMT) - Multiple Carrier Standard
iii) Multiple Carrie with G.lite - uses slower speeds but doesn't require the signals to be split at the subscriber end. Most popular method for mass market.
