Turbo receivers for interleave-division multiple-access systems [PDF]

open access: yes, 2009
In this paper several turbo receivers for Interleave-Division Multiple-Access (IDMA) systems will be discussed. The multiple access system model is presented first. The optimal, Maximum A Posteriori (MAP) algorithm, is then presented.

Spectrally Efficient Frame Format-Aided Turbo Equalization with Channel Estimation [PDF]

open access: yes, 2012
Chained turbo equalization (CHATUE) has been recently recognized as a low-complexity frequency domain turbo equalization technique that eliminates the necessity of transmitting the cyclic prefix (CP), and hence allows for spectrally efficient signalling ...

Maximum-LikelihoodSemiblind Equalization of Doubly Selective Channels Using the EM Algorithm

open access: yesEURASIP Journal on Advances in Signal Processing, 2010
Maximum-likelihood semi-blind joint channel estimation and equalization for doubly selective channels and single-carrier systems is proposed. We model the doubly selective channel as an FIR filter where each filter tap is modeled as a linear combination

Near-capacity three-stage MMSE turbo equalization using irregular convolutional codes

open access: yes, 2006
Traditional Turbo EQualization (TEQ) schemes suffer from residual bit errors due to the non-recursive nature of the channel imposing Inter-Symbol-Interference (ISI).

EXIT Chart-Aided Adaptive Coding for MMSE Turbo Equalization with Multilevel BICM [PDF]

open access: yes, 2006
This letter proposes adaptive coding (AC) for multilevel bit interleaved coded modulation (ML-BICM) with MMSE turbo equalization, of which aim is to minimize the information rate loss due to the mismatch between the channel realization and channel coding.

Chained Turbo Equalization for SC-FDMA Systems without Cyclic Prefix [PDF]

open access: yes, 2010
This paper proposes a novel Single Carrier Frequency Division Multiple Access (SC-FDMA) System without Cyclic Prefix based on the Chained Turbo Equalization (CHATUE) algorithm, which connects turbo equalizers neighboring in time to eliminate the Inter ...

Iterative Decoding of Concatenated Codes: A Tutorial

open access: yesEURASIP Journal on Advances in Signal Processing, 2005
The turbo decoding algorithm of a decade ago constituted a milestone in error-correction coding for digital communications, and has inspired extensions to generalized receiver topologies, including turbo equalization, turbo synchronization, and turbo ...
