On the Nonasymptotic Bounds of Joint Source-Channel Coding with Hierarchical Sources
Shuo Shao, Chao Qi, Jincheng Dai +2
This paper establishes tractable bounds of joint source-channel coding with hierarchical sources in the finite blocklength regime. In this setting, both the indirect source and obs…

Secure Joint Source-Channel Coding for the AWGN Channel with Feedback: A Finite Blocklength Analysis
Sheng Su, Yuhan Yang, Chao Qi +3
In the literature, it has been shown that the secrecy capacity of the additive white Gaussian noise (AWGN) wiretap channel with noise-free feedback equals the capacity of the same…

Coding for Fading Channels with Imperfect CSI at the Transmitter and Quantized Feedback
Yuhan Yang, Haoheng Yuan, Chao Qi +2
The classical Schalkwijk-Kailath (SK) scheme for the additive Gaussian noise channel with noiseless feedback is highly efficient since its coding complexity is extremely low and th…
