Abstract :
In this paper, we propose a graph-based soft iterative receiver (GSIR) for higher-order modulation. The performance characteristics of this kind of receiver is investigated via an EXIT chart analysis. Interpolation helps to provide reliable channel estimates for the whole data burst at the initialization stage. Additionally, our proposed receiver algorithm is compared with various interpolation-based initialization methods by Monte-Carlo simulations.
