Iterative Intercell Interference Cancellation for DL MC-CDMA Systems.

This paper investigates the cancellation of intercellular interference for downlink (DL) MC-CDMA systems. We especially focus on two turbo-iterative receiver schemes that allow cancellation of a part of the intercell interference. After deriving the block diagram receivers and the mathematical expressions at different receiver stages for both receivers, we present several link-level simulation results considering B3G multicellular scenario in presence of one interfering cell. We demonstrate the significant performance improvements of the proposed schemes over a wide signal to interference ratio (SIR) area at half and full loads. Index Terms—Iterative receiver, intercell interference, MC-CDMA. [ABSTRACT FROM AUTHOR]
