Blind turbo decoding and equalization
1999 IEEE 49th Vehicular Technology Conference (Cat. No.99CH36363), 2003We present two turbo decoding structure which combine channel equalization and decoding, allowing communication in the presence of intersymbol interference (ISI). The first one combines the trellis representing each one of the constituent encoders with the ISI trellis and performs slightly better that the second structure, which treats the ISI as ...

Turbo Equalization in Blind Receiver
2010 International Conference on Communications and Intelligence Information Security, 2010A turbo equalizer can benefit from channel decoding gain by iteratively performing equalization and channel de-coding. Turbo equalization algorithms always need perfect knowledge of the channel response. In this paper, we propose a blind turbo equalization and iterative channel estimator scheme. A fractional super-exponential blind equalizer is used to

Turbo equalizations for sparse channels
2004 IEEE Wireless Communications and Networking Conference (IEEE Cat. No.04TH8733), 2004Turbo equalization scheme provides nearly optimal performance but when it is employed in sparse multipath channel environments, the equalizer complexity can prohibit its use and develops a parallel trellis n-tap maximum a posteriori (MAP) equalizer, which can consider n dominant taps of sparse channels in the trellis with reasonable complexity.

A Low Complexity Turbo Equalizer
2005In 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), 2002This 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, 2006Abstract 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
2005The 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 ...
