Turbo Equalization With Irregular Turbo Codes [PDF]

open access: yes2007 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 ...

Sparse decision feedback equalization for underwater acoustic channel based on minimum symbol error rate

open access: yesInternational Journal of Naval Architecture and Ocean Engineering, 2021
Underwater Acoustic Channels (UAC) have inherent sparse characteristics. The traditional adaptive equalization techniques do not utilize this feature to improve the performance.

Soft-Decision-Driven Channel Estimation for Pipelined Turbo Receivers [PDF]

open access: yes, 1999
We consider channel estimation specific to turbo equalization for multiple-input multiple-output (MIMO) wireless communication. We develop a soft-decision-driven sequential algorithm geared to the pipelined turbo equalizer architecture operating on ...

Turbo Equalization: An Overview [PDF]

open access: yesIEEE Transactions on Information Theory, 2011
Turbo codes and the iterative algorithm for decoding them sparked a new era in the theory and practice of error control codes. Turbo equalization followed as a natural extension to this development, as an iterative technique for detection and decoding of data that has been both protected with forward error correction and transmitted over a channel with

Turbo DFE Assisted Time-Frequency Packing for Probabilistically Shaped Terabit Superchannels

open access: yesIEEE Photonics Journal, 2021
We present a probabilistically shaped (PS) time-frequency-packing (TFP) wavelength-division multiplexing superchannel system employing higher order modulation (HoM) formats, with an objective to improve the spectral efficiency (SE).

Weighted Multi-Band Turbo-Coded FSK for Reliable Underwater Communications

open access: yesApplied Sciences, 2022
Multi-band communication technology allocates the same data to different frequency bands, improving both performance and propagation efficiency. However, since the performance loss in a particular band affects the entire band, the multi-band structure ...

Near-capacity turbo equalization using optimized turbo codes [PDF]

open access: yes2007 Australasian Telecommunication Networks and Applications Conference, 2007
In this paper we analyze a turbo equalization scheme that combines maximum a posteriori probability (MAP) equalization and turbo decoding. Our aim is to optimize the turbo equalizer in order to approach the information capacity limit for channels with severe inter-symbol interference (ISI).
