A Low Complexity Turbo Equalizer

2005
In this paper a new Soft Input – Soft Output (SISO) equalizer of linear complexity is developed. The algorithm can be used in the so-called Turbo Equalization scheme as a low cost solution in place of the Maximum A-Posteriori (MAP) equalization algorithm which has a prohibitive complexity for most real world applications.

Joint turbo equalization and turbo TCM for mobile communication systems

12th IEEE International Symposium on Personal, Indoor and Mobile Radio Communications. PIMRC 2001. Proceedings (Cat. No.01TH8598), 2002
This paper deals with a new receiver scheme that combines turbo equalization and turbo trellis coded modulation (turbo TCM). This receiver serially concatenates a soft input soft output (SISO) equalizer and a soft-out symbol-by-symbol MAP turbo TCM decoder through an iterative process. In certain cases, the joint turbo equalization and turbo TCM scheme

Reduced-Complexity Turbo Equalization for Turbo Coded MIMO/OFDM Systems

The Journal of China Universities of Posts and Telecommunications, 2006
Abstract This paper derives a low-complexity turbo equalization algorithm for turbo coded multiple input multiple output/orthogonal frequency division multiplexing systems. This algorithm consists of soft-output decision-feedback equalization with a probabilistic data association algorithm and a soft-input soft-output turbo channel decoder using ...

Turbo Equalization without MMSE Filtering

2005
The filter-based turbo equalization scheme has been proposed in several papers to avoid the prohibitive complexity imposed by the trellis-based turbo equalization. In the existing literature,the filter-based approach has been solely implemented by a linear MMSE filter, the coeffi cients of which are updated to minimize the mean-square error for every ...

Turbo-Equalized FTN-Inspired Modulations

New modulations are sought for 6G radio mobile systems, based on partial response signaling, have been invented recently. The characteristics of these modulations have been thoroughly investigated and assessed and very promising results have been obtained. The next step following this characterization work is to introduce coding into the picture.
