Space-Time Trellis and Space-Time Block Coding Versus Adaptive Modulation and Coding Aided OFDM for Wideband Channels

open access: yes, 2006
—The achievable performance of channel coded spacetime trellis (STT) codes and space-time block (STB) codes transmitted over wideband channels is studied in the context of schemes having an effective throughput of 2 bits/symbol (BPS) and 3 BPS.

Helper Data Schemes for Coded Modulation and Shaping in Physical Unclonable Functions

open access: yesIEEE Open Journal of the Communications Society
We consider the generation and utilization of helper data for physical unclonable functions (PUFs) that provide real-valued, Gaussian distributed readout symbols.

Zernike Moment-Based Spatial Image Steganography Resisting Scaling Attack and Statistic Detection

open access: yesIEEE Access, 2019
The mainstream adaptive steganography algorithm is difficult to resist scaling attack, and the anti-detection performance of the algorithm based on quantization index modulation is not high enough.

New 16-PSK trellis codes for fading channels [PDF]

open access: yes
Growth in satellite mobile communications leads to increasing requirements for high data rate transmission that can be met by more efficient modulation schemes (M greater than 8). The 16-PSK trellis coded modulation technique is a very promising solution.

New Trellis Code Design for Spatial Modulation

open access: yesIEEE Transactions on Wireless Communications, 2011
Spatial modulation (SM), in which multiple antennas are used to convey information besides the conventional M-ary signal constellations, is a new multiple-input multiple-output (MIMO) transmission technique, which has recently been proposed as an alternative to V-BLAST (vertical Bell Labs layered space-time).
