Sliding-Window Turbo Equalization and Its Reduced-Complexity Decoding Techniques
IEEE Access, 2022 Turbo equalization is a cooperative error-correcting approach to achieve a target bit-error rate over inter-symbol interference channels. In this paper, we proposed a new turbo equalization, called sliding-window turbo equalization (SW-TE), consisting of

Turbo Equalization With Irregular Turbo Codes [PDF]
2007 4th International Symposium on Wireless Communication Systems, 2007 We analyze a turbo equalization system that combines maximum a posteriori probability (MAP) equalization with irregular turbo codes. Our goal is to approach the information capacity limit for severe inter-symbol interference (ISI) channels. To this end, we optimize the degree profile of irregular turbo codes by maximizing the minimum distance between ...

Spatial Coupling In Turbo Equalization
GLOBECOM 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 ...

Fully Parallel Turbo Equalization for Wireless Communications
IEEE 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).
