Abstract

In this paper, the problem of adaptive iterative detection for parallel concatenated convolutional codes (PCCCs or turbo codes) in the presence of carrier-phase uncertainty is examined. In particular, a subclass of adaptive iterative receivers, based on the adaptive soft-input soft-output (A-SISO) algorithms is presented. Several design options are proposed and compared and the impact of parametric uncertainty on previously established results for iterative detection with perfect channel state information (CSI) is assessed.
