Abstract :
We compare two structures for combined equalization/detection of linear codes over frequency selective channels. The structures come from different families of codes: convolutional codes on one hand and parity check block codes on the other hand. First, we show that the joint receiver process corresponds to an iterative belief propagation schedule on graphical representations. Then, we draw and comment upon the simulation results for various codes and channel choices
