Abstract :
The authors provide a quantitative performance comparison of selected digital transmission schemes proposed for providing reliable communication on two-wire twisted-pair digital subscriber loops in support of ISDN (integrated services digital network) services. More specifically, they consider the bit error probability (BEP) performance of both hybrid adaptive echo cancellation (HAEC) and time compression multiplexing (TCM) schemes employing either AMI or 2B1Q line codes. The modeling assumptions are carefully described and used to develop a quantitative relative-performance evaluation methodology. Numerical results illustrate the nature of the performance trade-offs as a function of channel and system design parameters. These results are useful in characterizing the parameter choices when there is a clear preference for one system over another
