tion/estimation problems and then deriving ecient turbo-like iterative algo-
rithms for solving them. The interested reader will find good overviews of factor
graphs and their applications in [11.37] and [11.38]. The use of factor graphs in a
turbo equalization context has been considered in particular in [11.22] et[11.16]
and an in-depth study of multi-user detection from a factor graph perspective
has been presented in [11.10].
