Turbo Equalization: An Overview [PDF]
IEEE 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

Combined turbo equalization and turbo decoding [PDF]
IEEE Communications Letters, 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 ...

Adaptive Equalization in a Turbo Loop
IEEE Transactions on Wireless Communications, 2015 Turbo equalization has been an important topic in wireless communication for some time. Various approaches to incorporating the a priori information from the decoder into the equalization process have been developed. In this paper, we present and investigate an algorithm for adaptive equalization in a turbo loop.
