  • Abstract
    A 128 state 4D TCM code for ADSL assuming AWGN is analyzed. The performance is compared with 16 state (3, 2, 5) linear 4D code developed by L. F. Wei [1]. Simulation shows an improvement of 20% in spectral efficiency. We have also analyzed 8-DMT symbol based decoding for Wei´s code 16 state (3, 2, 5) in up stream direction and achieved .9 db gain.
