Spatial Coupling In Turbo Equalization

open access: greenGLOBECOM 2020 - 2020 IEEE Global Communications Conference, 2020
In this paper we consider spatial coupling in turbo equalization and demonstrate that the code design trade-off between the performance in waterfall and error floor regions can be avoided. We introduce three coupling schemes and compare their performances, where the first method introduces coupling between the encoder and the channel, while the second ...

A new SISO algorithm with application to turbo equalization [PDF]

open access: green, 2005
In this paper we propose a new soft-input soft-output equalization algorithm, offering very good performance/complexity tradeoffs. It follows the structure of the BCJR algorithm, but dynamically constructs a simplified trellis during the forward ...

Fully Parallel Turbo Equalization for Wireless Communications

open access: yesIEEE Access, 2015
Iterative turbo equalization is capable of achieving impressive performance gains over the conventional non-iterative equalization having the same complexity, when communicating over channels that suffer from intersymbol interference (ISI).

Iterative Estimation in Turbo Equalization Process [PDF]

open access: greenJournal of Electrical and Electronics Engineering, 2014
This paper presents the iterative estimation in turbo equalization process. Turbo equalization is the process of reception in which equalization and decoding are done together, not as separate processes.

Combined turbo equalization and turbo decoding [PDF]

open access: yesGLOBECOM 97. IEEE Global Telecommunications Conference. Conference Record, 1998
In this paper, the subject of turbo coding in the presence of intersymbol interference channel is investigated. An iterative decoder structure is presented, which combines the channel equalization and the turbo decoding. At each iteration extrinsic information from the channel detector is fed into the turbo decoders, and then their extrinsic ...
