Scenario-Adaptive Deep Joint Source-Channel Coding for CSI Feedback

IEEE Open Journal of the Communications Society
Multiple-input multiple-output (MIMO) technology is expected to be a critical technology for next-generation wireless communication systems. A major challenge in frequency division duplexing (FDD) MIMO systems is the realization of low-overhead, high ...

Deep Learning-Constructed Joint Transmission-Recognition for Internet of Things

IEEE Access, 2019
The widely deployed Internet-of-Things (IoT) devices provide intelligent services with its cognition capability. Since the IoT data are usually transmitted to the server for recognition (e.g., image classification) due to low computational capability and

DRASIC: Distributed Recurrent Autoencoder for Scalable Image Compression

, 2019
We propose a new architecture for distributed image compression from a group of distributed data sources. The work is motivated by practical needs of data-driven codec design, low power consumption, robustness, and data privacy. The proposed architecture,

EM based channel estimation in an amplify-and-forward relaying network [PDF]

, 2010
Cooperative communication offers a way to obtain spatial diversity in a wireless network without increasing hardware demands. The different cooperation protocols proposed in the literature [1] are often studied under the assumption that all channel state

Deciphering transcriptional plasticity in pancreatic ductal adenocarcinoma reveals alterations in sensory neuron innervation

Molecular Oncology, EarlyView.
Pancreatic sensory neurons innervating healthy and PDAC tissue were retrogradely labeled and profiled by single‐cell RNA sequencing. Tumor‐associated innervation showed a dominant neurofilament‐positive subtype, altered mitochondrial gene signatures, and reduced non‐peptidergic neurons.

5G Indoor/Outdoor Field Trial of Deep Joint Source-Channel Coding Method

IEEE Open Journal of the Communications Society
This paper presents the first outdoor field trials of deep joint source-channel coding (DeepJSCC) for image transmission over a 5G system. DeepJSCC is a deep learning-based end-to-end method that unifies source and channel coding to enable robust and low-

Concatenated Turbo/LDPC codes for deep space communications: performance and implementation [PDF]

, 2013
Deep space communications require error correction codes able to reach extremely low bit-error-rates, possibly with a steep waterfall region and without error floor. Several schemes have been proposed in the literature to achieve these goals.

Analysis of cyclic delay diversity on DVB-H systems over spatially correlated channel [PDF]

, 2007
The objective of this work is to research and analyze the performance of Cyclic Delay Diversity (CDD) with two transmit antenna on DVB-H systems operating in spatially correlated channel. It is shown in this paper that CDD can achieve desirable transmit

Deep Joint Source-Channel Coding for Wireless Point Cloud Transmission

ICASSP 2025 - 2025 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)
The growing demand for high-quality point cloud transmission over wireless networks presents significant challenges, primarily due to the large data sizes and the need for efficient encoding techniques. In response to these challenges, we introduce a novel system named Deep Point Cloud Semantic Transmission (PCST), designed for end-to-end wireless ...
