EXIT chart analysis for iterative timing recovery

Performance analysis of iterative timing recovery schemes, which perform timing recovery, equalization, and error-correction decoding jointly, is difficult because of their complexity. In this paper, we apply the extrinsic information transfer chart (EXIT chart) analysis as a tool to compare and predict their performances. Simulation results indicate that the system performance predicted by the EXIT chart coincides with that obtained by simulating data transmission over a complete iterative receiver, especially when the coded block length is large.
