Analog Slice Turbo Decoding [PDF]

open access: yes2005 IEEE International Symposium on Circuits and Systems, 2005
This paper presents the design of an analog turbo decoder for DVB-RCS-like applications using a slice architecture. The constituent decoders for different frame lengths are made up of duplicated elements chosen from a small set of reduced-size MAP decoders.

Extrinsic Information Modification in the Turbo Decoder by Exploiting Source Redundancies for HEVC Video Transmitted Over a Mobile Channel

open access: yesIEEE Access, 2016
An iterative turbo decoder-based cross layer error recovery scheme for compressed video is presented in this paper. The soft information exchanged between two convolutional decoders is reinforced both by channel coded parity and video compression ...
