The Journal of Engineering, Volume 2014, Issue 8, Page 391-398, August 2014., 2014 This study presents research that supplements and extends the previous works on design of space‐time fully systematic unpunctured (FSU) serial concatenation of quadratic interleaved codes (SCQICs). The requirements for efficient design of the forward error correction (FEC) codecs motivated potential information‐theoretic studies for enjoying the ...

Two‐Dimensional Iterative Processing for DAB Receivers Based on Trellis‐Decomposition
Journal of Electrical and Computer Engineering, Volume 2012, Issue 1, 2012., 2012 We investigate iterative trellis decoding techniques for DAB, with the objective of gaining from processing 2D‐blocks in an OFDM scheme, that is, blocks based on the time and frequency dimension, and from trellis decomposition. Trellis‐decomposition methods allow us to estimate the unknown channel phase since this phase relates to the sub‐trellises. We

VLSI Architectures for Sliding‐Window‐Based Space‐Time Turbo Trellis Code Decoders
Journal of Electrical and Computer Engineering, Volume 2012, Issue 1, 2012., 2012 The VLSI implementation of SISO‐MAP decoders used for traditional iterative turbo coding has been investigated in the literature. In this paper, a complete architectural model of a space‐time turbo code receiver that includes elementary decoders is presented.
