Turbo-equalization considering bit-interleaved turbo-coded modulation: performance bounds

The goal of this paper is to assess the performance of turbo-equalization (TE), considering at the transmitter bit-interleaved coded modulation (BICM) with a turbo-code as error-correcting code. The bounding techniques that we have recently proposed in Dejonghe et al. (2004) are extended to this particular problem. Simulation results show the relevance of the proposed bounds. By the way, this leads to analytical tools for the understanding and optimization of such turbo-systems.
