| Abstract(in English) | We derive EXIT functions and perform EXIT analysis for a belief-propagation (BP) based CDMA detection algorithm under the random spreading assumption and in the large-system limit. On deriving the EXIT functions, in order to represent them appropriately, we propose introduction of an appropriate scale transform. The EXIT analysis based on EXIT functions gives us an efficient visual representation of the macroscopic dynamics of the algorithm. |
