Improved Max-Log-MAP Turbo Decoding by Maximization of Mutual Information Transfer
EURASIP Journal on Advances in Signal Processing, 2005 The demand for low-cost and low-power decoder chips has resulted in renewed interest in low-complexity decoding algorithms. In this paper, a novel theoretical framework for improving the performance of turbo decoding schemes that use the max-log-MAP ...

EURASIP Journal on Advances in Signal Processing, 2006 In this contribution we propose an analogue receiver that can perform turbo detection in MIMO systems. We present the case for a receiver that is built from nonlinear analogue devices, which perform detection in a "free-flow" network (no notion of ...
