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.

Distributed Source Coding and Its Applications in Relaying-Based Transmission
IEEE Access, 2016 Distributed source coding (DSC) schemes rely on separate encoding but joint decoding of statistically dependent sources, which exhibit correlation. DSC has numerous promising applications ranging from reduced-complexity handheld video communications to ...

International Journal of Antennas and Propagation, Volume 2011, Issue 1, 2011., 2011 A new technique that combines adaptive power allocation and iterative detection based on singular value decomposition (SVD) is introduced for the modified Turbo‐BLAST system with imperfect channel state information (I‐CSI). At the transmitter, in order to maximize the capacity performance, the MIMO channel is decomposed into several parallel eigen ...

Comparative study of turbo coded wideband adaptive modulation and space-time trellis codes [PDF]
Vehicular Technology Conference. IEEE 55th Vehicular Technology Conference. VTC Spring 2002 (Cat. No.02CH37367), 2003 The decision feedback equaliser (DFE) aided turbo coded wideband adaptive quadrature amplitude modulation (AQAM) is capable of accommodating the temporal channel quality variation of fading channels. By contrast, the family of multiple-input-multiple-output (MIMO) DFE aided space-time trellis codes benefits from transmit diversity and hence it is ...

Serial turbo trellis coded modulation with rate-1 inner code [PDF]
2000 IEEE International Symposium on Information Theory (Cat. No.00CH37060), 2002 We develop new, low-complexity turbo codes suitable for bandwidth and power limited systems. These codes are constructed as an extension of repeat-accumulate codes to high-level-modulations. Two design criteria are proposed, based on maximum-likelihood decoding and on Gaussian density evolution in iterative decoding.

Joint Multilevel Turbo Equalization and Continuous Phase Frequency Shift Keying
EURASIP Journal on Wireless Communications and Networking, 2008 A novel type of turbo coded modulation scheme, called multilevel turbo coded-continuous phase frequency shift keying (MLTC-CPFSK), is designed to improve the overall bit error rate (BER) and bandwidth efficiency. Then, this scheme is combined with a new

Turbo-encoder design for symbol-interleaved parallel concatenated trellis-coded modulation [PDF]
IEEE Transactions on Communications, 2001 Summary: This paper addresses turbo-encoder design for coding with high spectral efficiency using parallel concatenated trellis-coded modulation and symbol interleaving. The turbo-encoder design involves the constituent encoder design and the interleaver design. The constituent encoders are optimized for symbolwise effective free distance, and each has

Performance Evaluation of Parallel Concatenated Chaos Coded Modulations
Journal of Communications Software and Systems, 2008 In this article we study the performance of a class of parallel concatenated encoders similar to a turbo trellis coded modulation, but where the constituent encoders are chaos coded modulators.
