A Dual-Path TEQ Structure for DMT-ADSL Systems
Overview Discrete Multitone (DMT) modulation is the industry standard for Asymmetrical Digital Subscriber Loop (ADSL) modems. DMT modulation allows for simplified equalization when the effective duration of the channel memory is shorter that the predefined length of the cyclic prefix (CP). A single time-domain equalizer (TEQ) is typically used to truncate the channel memory such that the data rate loss due to the use of the CP is reduced. Because the single TEQ is optimized over all subchannels, it is difficult to find an ideal solution in which the number of bits supported on each subchannel is optimized.
