We describe a fairly general class of iterative receivers for multiple-antenna systems. These receivers combine a soft decoder for a space-time code with a spatial-interference canceler. The performance of these receivers is analyzed by using EXIT charts, a convenient graphical description that yields quite accurate results. By properly combining the EXIT characteristics of the canceler and of the decoder, the convergence behavior of the iterative algorithms can be understood, and design guidelines derived.

Abstract
We describe a fairly general class of iterative receivers for multiple-antenna systems. These receivers combine a soft decoder for a space-time code with a spatial-interference canceler. The performance of these receivers is analyzed by using EXIT charts, a convenient graphical description that yields quite accurate results. By properly combining the EXIT characteristics of the canceler and of the decoder, the convergence behavior of the iterative algorithms can be understood, and design guidelines derived.File in questo prodotto:
