DeepWiVe: Deep-Learning-Aided Wireless Video Transmission

no code implementations25 Nov 2021 Tze-Yang Tung, Deniz Gündüz

We present DeepWiVe, the first-ever end-to-end joint source-channel coding (JSCC) video transmission scheme that leverages the power of deep neural networks (DNNs) to directly map video signals to channel symbols, combining video compression, channel coding, and modulation steps into a single neural transform.

DeepJSCC-f: Deep Joint Source-Channel Coding of Images with Feedback

4 code implementations25 Nov 2019 David Burth Kurka, Deniz Gündüz

It is well known that separation is not optimal in the practical finite blocklength regime; however, there are no known practical joint source-channel coding (JSCC) schemes that can exploit the feedback signal and surpass the performance of separation-based schemes.

Energy-Aware Analog Aggregation for Federated Learning with Redundant Data

Deep Convolutional Compression for Massive MIMO CSI Feedback

no code implementations2 Jul 2019 Qianqian Yang, Mahdi Boloursaz Mashhadi, Deniz Gündüz

In comparison with previous works, the main contributions of DeepCMC are two-fold: i) DeepCMC is fully convolutional, and it can be used in a wide range of scenarios with various numbers of sub-channels and transmit antennas; ii) DeepCMC includes quantization and entropy coding blocks and minimizes a cost function that accounts for both the rate of compression and the reconstruction quality of the channel matrix at the BS.
