Streaming Data Transmission in the Moderate Deviations and Central Limit Regimes
Si-Hyeon Lee, Vincent Y. F. Tan, Ashish Khisti
We consider streaming data transmission over a discrete memoryless channel. A new message is given to the encoder at the beginning of each block and the decoder decodes each messag…
Secure Degrees of Freedom of the Gaussian Diamond-Wiretap Channel
Si-Hyeon Lee, Wanyao Zhao, Ashish Khisti
In this paper, we consider the Gaussian diamond-wiretap channel that consists of an orthogonal broadcast channel from a source to two relays and a Gaussian fast-fading multiple acc…
Information-Theoretic Privacy for Smart Metering Systems with a Rechargeable Battery
Simon Li, Ashish Khisti, Aditya Mahajan
Smart-metering systems report electricity usage of a user to the utility provider on almost real-time basis. This could leak private information about the user to the utility provi…
The MIMO Wiretap Channel Decomposed
Anatoly Khina, Yuval Kochman, Ashish Khisti
The problem of sending a secret message over the Gaussian multiple-input multiple-output (MIMO) wiretap channel is studied. While the capacity of this channel is known, it is not c…
Convolutional Codes with Maximum Column Sum Rank for Network Streaming
Rafid Mahmood, Ahmed Badr, Ashish Khisti
The column Hamming distance of a convolutional code determines the error correction capability when streaming over a class of packet erasure channels. We introduce a metric known a…
The Degraded Gaussian Diamond-Wiretap Channel
Si-Hyeon Lee, Ashish Khisti
In this paper, we present nontrivial upper and lower bounds on the secrecy capacity of the degraded Gaussian diamond-wiretap channel and identify several ranges of channel paramete…
