Super-orthogonal trellis-coded spatial modulation

open access: yesIET Communications, 2012
Spatial modulation (SM), which employs the indices of multiple transmit antennas to transmit information in addition to the conventional M-ary signal constellations, is a novel transmission technique that has been proposed for multiple-input multiple-output systems.

Trellis Coded 4-ary PAM using Distance-Preserving Mapping [PDF]

open access: yesInternational Journal of Electronics and Telecommunications, 2018
A trellis coded 4-ary Pulse Amplitude Modulation (4-PAM) is presented, where the encoding algorithm is derived from Distance Preserving Mapping (DPM) algorithm. In this work, we modify the DPM algorithm for 4-PAM and obtain a new construction for mapping

Nonbinary LDPC-Coded Modulation for High-Speed Optical Fiber Communication Without Bandwidth Expansion

open access: yesIEEE Photonics Journal, 2012
We propose a scheme that can attain the same transmission bit rate as the corresponding conventional polarization-division-multiplexed (PDM) quadrature amplitude modulation (QAM) scheme while occupying lower bandwidth and, hence, achieving a higher ...

Joint trellis-coded quantisation/modulation

open access: yesElectronics Letters, 2000
Joint trellis-coded quantisation (TCQ) and trellis-coded modulation (TCM) can achieve considerable signal-to-quantisation noise ratios with moderate complexity. TCM is replaced with turbo TCM (TTCM) and simulation results given which show that the new scheme can achieve the same performance as that possible using by trellis-coded scalar quantisation at

Adaptive Turbo Trellis Coded Modulation Aided Distributed Space-Time Trellis Coding for Cooperative Communications [PDF]

open access: yes2010 IEEE 71st Vehicular Technology Conference, 2010
In this contribution, we propose an adaptive Turbo Trellis Coded Modulation (TTCM) aided Distributed Space-Time Trellis Coding (STTC) scheme for cooperative communication over quasi-static Rayleigh fading channels. An adaptive TTCM (ATTCM) scheme is employed by the source node during the first transmission period for reliably conveying the source bits ...

Repeat-punctured turbo trellis-coded modulation [PDF]

open access: yesIEEE Africon '11, 2011
In this paper repeat-punctured turbo trellis-coded modulation (RPTTCM) is proposed. In RPTTCM, the effect of repeat-puncture is investigated on a TTCM system, repetition of the information bits increases the interleaver size, followed by an appropriate puncturing scheme to maintain the respective code rate.

Mapping Rearrangement for Parallel Concatenated Trellis Coded Modulation

open access: yesEURASIP Journal on Wireless Communications and Networking, 2008
Mapping rearrangement (MaRe) for the hybrid ARQ (HARQ) based on the parallel concatenated trellis coded modulation (PCTCM) is analyzed. We demonstrate that the performance of the PCTCM receiver is intrinsically limited by the MaRe design and we propose a

A Low-Complexity Approach to Space-Time Coding for Multipath Fading Channels

open access: yesEURASIP Journal on Wireless Communications and Networking, 2005
We consider a single-carrier multiple-input single-output (MISO) wireless system where the transmitter is equipped with multiple antennas and the receiver has a single antenna.
