Abstract
The authors show that the hybrid digital-analog (HDA) systems outperform the tandem system and the analog system (at high SNRs). In particular they note the graceful improvement of the HDA systems, as opposed to the leveling-off in performance of the tandem system. They also observe that the performance can be improved at low SNRs using the optimization procedure
