Exit charts for turbo receivers in MIMO systems
نویسندگان
چکیده
Iterative exchange of information between a decoder and a front end receiver was shown to improve the performance when comparing to non-iterative approach. This so-called turbo processing may be described using Extrinsic Information Transfer (EXIT) charts which were already used in case of turbo decoders and turbo-equalizers. This work extends the EXIT charts technique to describe the behavior of MIMO narrowband turbo receivers and explains the main difficulties in the EXIT analysis for Rayleigh fading channels

Wireless broadband single-carrier systems with MMSE turbo equalization receivers
Broadband single-carrier modulated signals experience severe multipath distortion when propagating through the physical medium. Correcting the distortion with channel equalization is the foremost task of the detector. Prior information about the transmitted signals in the form of channel decoder feedback can significantly enhance equalization accuracy. An algorithm that iteratively performs cha...
متن کاملTurbo detection for MIMO systems: bit labeling and pre-coding
Bit-interleaved coded modulation with iterative detection for MIMO systems demands an efficient APP detector that delivers soft information about the coded bits. The list-sequential detector is a reduced-complexity approximation to an exhaustive APP detector. It uses a tree search employing the stack algorithm to find dominant terms of the log-likelihood ratio. The commonly used symbol-by-symbo...
متن کاملThe Turbo Principle in Mobile Communications
This overview talk shows that the so-called turbo codes(decoders) entail a much broader principle. It discusses how the feedback of extrinsic information which we call the turbo principle can be used in many mobile communications receivers to improve performance through iterative processing. As an analysis and design tool the EXIT charts of mutual information transfer are used.
متن کاملComplexity Reduction in Iterative MIMO Receivers Based on EXIT Chart Analysis
The application of the Turbo principle in MIMO receivers allows to achieve near-capacity performance with a number of different MIMO detection algorithms. However, this high performance is paid for by a substantial increase in complexity, as detector and decoder have to be run multiple times. In this paper, we show that an analysis of detector and decoder transfer curves in the EXIT chart can b...
متن کاملIterative receivers for coded MIMO signaling
In this tutorial paper we describe iterative receivers that combine a soft decoder for a general space–time code with a spatialinterference 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...
