Combined turbo equalization and turbo decoding [PDF]
GLOBECOM 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 ...

DEEPTURBO: Deep Turbo Decoder [PDF]
2019 IEEE 20th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2019 Present-day communication systems routinely use codes that approach the channel capacity when coupled with a computationally efficient decoder. However, the decoder is typically designed for the Gaussian noise channel and is known to be sub-optimal for non-Gaussian noise distribution.

On the Convergence Speed of Turbo Demodulation With Turbo Decoding [PDF]
IEEE Transactions on Signal Processing, 2012 Iterative processing is widely adopted nowadays in modern wireless receivers for advanced channel codes like turbo and LDPC codes. Extension of this principle with an additional iterative feedback loop to the demapping function has proven to provide substantial error performance gain.
