Trellis-coded multidimensional phase modulation
IEEE Transactions on Information Theory, 1990 A 2L-dimensional multiple phase-shift keyed (L*MPSK) signal set is obtained by forming the Cartesian product of L two-dimensional MPSK signal sets. A systematic approach to partitioning L*MPSK signal sets that is based on block coding is used. An encoder system approach is developed.

Advanced Science, Volume 13, Issue 21, 13 April 2026.Dry soft Ti3C2Tx MXene electroencephalography (EEG) electrodes provide low impedance (2.1 ± 1.8 kΩ at 10 Hz), long‐term stability, and enable safe simultaneous EEG and transcranial magnetic stimulation (TMS). Across scalp sites, hair types, and recording paradigms, including steady state visual evoked potentials (SSVEP), clinical EEG, and mobile EEG ...

Modified SNR Gap Approximation for Resource Allocation in LDPC-Coded Multicarrier Systems
IEEE Access, 2020 The signal-to-noise ratio (SNR) gap approximation provides a closed-form expression for the SNR required for a coded modulation system to achieve a given target error performance for a given constellation size. This approximation has been widely used for

Trellis-Coded Non-Orthogonal Multiple Access [PDF]
, 2019 In this letter, we propose a trellis-coded non-orthogonal multiple access (NOMA) scheme. The signals for different users are produced by trellis coded modulation (TCM) and then superimposed on different power levels.

Australian Journal of Grape and Wine Research, Volume 2026, Issue 1, 2026.Background and Aims Climate change and reduced precipitation pose significant challenges for the wine industry, particularly in vulnerable regions, where it is essential to incorporate irrigation management tools. Regulated deficit irrigation (RDI) is a step forward in that direction.

Combined Source-Channel Coding of Images under Power and Bandwidth Constraints
EURASIP Journal on Advances in Signal Processing, 2007 This paper proposes a framework for combined source-channel coding for a power and bandwidth constrained noisy channel. The framework is applied to progressive image transmission using constant envelope M-ary phase shift key (M-PSK) signaling over an ...
