چکیده
Joint iterative equalization and decoding is a very successful approach to dealing with severe inter-symbol interference in band limited communication channels. We propose and investigate adaptive iterative methods that yield performance close to Turbo equalization while requiring considerably smaller complexity.

Iterative correction of ISI via equalization and decoding with priors - International Symposium on Information Theory, 2000. Proceedings. IEEE
Abstmct An iterative algorithm is presented for joint equalization and decoding of data that has been transmitted over intersymbol interference (ISI) channels. This differs from well-known “turbo e q u a l h tion” (TEQ) methods, in that the IS1 is removed with a soft-input soft-output (SISO) equalizer via linear or decision feedback equalization (DFE). The data is encoded with a convolutional c...
متن کاملTurbo equalization - Signal Processing Magazine, IEEE
apitalizing on the tremendous per formance gains of turbo codes and the turbo decoding algorithm, turbo equalization is an iterative equalization and decoding technique that can achieve equally impressive performance gains for communication systems that send digital data over channels that require equalization, i.e., those that suffer from intersymbol interference (ISI). In this article, we dis...
متن کاملIterative Joint Equalization and Decoding based on Soft Cholesky Equalization for General Complex Valued Modulation Symbols
A new iterative equalizer based on the classical block decision feedback equalizer is derived. The performance of this equalizer benefits from the usage of a soft decision function, which is based on noise whitening and consecutive matched filtering. The derivation of the decision function is very general and therefore applicable to arbitrary complex valued modulation symbols. After adding the ...
متن کاملTurbo equalization: adaptive equalization and channel decoding jointly optimized
This paper deals with a receiver scheme where adaptive equalization and channel decoding are jointly optimized in an iterative process. This receiver scheme is well suited for transmissions over a frequency-selective channel with large delay spread and for high spectral efficiency modulations. A low-complexity soft-input soft-output -ary channel decoder is proposed. Turbo equalization allows in...
متن کاملComdined Turbo Block Decoding and Equalisation
In this paper, the combination of equalization and turbo decoding is studied. In the iterative decoding of a product code in block turbo coding system, the equalization process is performed within the iteration loop. The present study aims to investigate the decision feedback equalizer (DFE) incorporated in the iterative decoding. Simulation results show that the more severe the channel interfe...
