Convergence Analysis for Linear Turbo Equalization
Absfracl-In this paper, we propose a method for analysis of linear turbo equalization that makes use of extrinsic information transfer (EXIT) charts. Given channel knowledge and a timeinvariant set oi linear equalizer coefficients, evolution of soft information in the soft-input soft-output (SISO) equalizer can be estimated via analytically measuring the mutual inionnation between the transmitt...
متن کاملEXIT Charts
With wide applications of Turbo Principle in communications engineering, the EXIT Charts (Extrinsic Information Transfer Charts) has been a powerful tool to visualize the convergence behavior of iterative decoding process based on mutual information. Within this report, an introduction to EXIT Charts, its background, properties and applications are presented to allow the audience be familiar wi...
متن کاملEXIT-Chart Based Labeling Design for Type-I HARQ in BICM-ID Systems
This paper investigates the issue of labeling design in the BICM-ID (bitinterleaved coded modulation-iterative decoding) systems with Type-I HARQ (hybrid auto-retransmission request). Based on the EXIT (extrinsic information transfer) chart, an algorithm is developed in search of good labelings that well match with the outer code. The concept of link adaptation is realized by using different la...
متن کاملTurbo Multiuser Detection Architectures
The discovery of Turbo Codes in 1996 by Berrou et. al. proved to be a huge boost for the research of channel coding. The Turbo Principle behind turbo codes was found to be applicable in other areas. One of these areas is Multiuser Detection. In this thesis, Turbo Multiuser Detection is investigated in order to answer two main questions. The questions concern the performance gain that is obtaine...
متن کاملAnalysis Tools for Iterative Source-Channel Decoding
We consider the problem of transmitting a correlated Gaussian source over an AWGN channel. This paper contains two main contributions which aid in the design of such a system. We determine the characteristic curves of the source decoder for use in the extrinsic information transfer charts (EXIT charts) and show how the characteristic curves vary with the amount of correlation in the source. Fur...
