摘要：
A multidimensional 16-state Trellis Coded Modulation (MTCM) is given as an option in Asymmetric Digital Subscriber Lines (ADSL) standard based on discrete multitone (DMT) techniques. To further improve the a transmission performance, instead of this MTCM, we propose to use bandwidth efficient turbo trellis coded modulation (TTCM) in ADSL DMT systems. In this paper; we show that by using turbo codes, we can obtain 6 dB coding gain for a bit error rate (BER) of 10(-6) in AWGN channels and more than 6.8 dB coding gain for a BER of 10(-7) using a concatenated coding scheme.
