Ternary Trellis Coded Modulation [PDF]

IEEE Access, 2019
Ternary trellis coded modulation (TTCM) is introduced. This combines triangular signal constellations with ternary convolutional codes. The performance of TTCM is presented and compared with binary trellis coded modulation (BTCM) which employs square ...

Potential Targets and Signaling Mechanisms of Cinnamaldehyde Enhancing Intestinal Function and Nutritional Regulation in Fat Greenling (Hexagrammos otakii). [PDF]

Aquac Nutr
Cinnamaldehyde is an ideal feed additive with good immune enhancement and anti‐inflammatory regulation effects. However, the anti‐inflammatory regulation mechanism in fat greenling (Hexagrammos otakii, H. otakii) remains unclear. The nine targets of cinnamaldehyde were gathered in identified by the Traditional Chinese Medicine Systems Pharmacology ...

Trellis Coded Spatial Modulation [PDF]

IEEE Transactions on Wireless Communications, 2010
Trellis coded modulation (TCM) is a well known scheme that reduces power requirements without any bandwidth expansion. In TCM, only certain sequences of successive constellation points are allowed (mapping by set partitioning). The novel idea in this paper is to apply the TCM concept to the antenna constellation points of spatial modulation (SM).

Characterization of irrigator emitter to be used as solid set canopy delivery system: which is best for which role in the vineyard?

Pest Management Science, Volume 79, Issue 2, Page 584-597, February 2023., 2023
Irrigator emitters were demonstrated as a feasible SSCD solution for PPP spray application in vineyards. The right emitter positioning in the canopy, according to their spray pattern, plays a key role for the canopy spray coverage. Abstract Background The timely and flexible treatment of solid set canopy delivery systems (SSCDS) is expanding ...

Studying and Modeling the Performance of the TCM-STBC Systems in the Rayleigh Channel

Journal of Telecommunications and Information Technology, 2021
Multiple-input multiple-output (MIMO) systems will play an important role in future generations of wireless networks. Space-time block code (STBC) and space-time trellis code (STTC) are two techniques that may be used in multiantenna radio systems. This

A bottom‐up design methodology of neural min‐sum decoders for LDPC codes

IET Communications, Volume 17, Issue 3, Page 377-386, February 2023., 2023
After investigating the training process of neural network formed by unrolling a original LDPC code decoder, we proposed a novel method of generating the needed feeding data, and exposed the close connection between loss and decoding metrics of a code. Furthermore, it was verified in extensive simulation that the quantity of training parameter impacts ...

A new design of channel denoiser using residual autoencoder

Electronics Letters, Volume 59, Issue 2, January 2023., 2023
A novel denoiser based on a residual autoencoder structure is proposed. The proposed denoiser speeds up training process and boosts the performance due to its structure effectively extracting compressed features. Simulation results show that this denoiser outperforms all the existing denoisers.
