MIMO Broadcast Channel with an Unknown Eavesdropper: Secrecy Degrees of Freedom
Xiang He, Ashish Khisti, Aylin Yener
We study a multi-antenna broadcast channel with two legitimate receivers and an external eavesdropper. We assume that the channel matrix of the eavesdropper is unknown to the legit…
Layered Constructions for Low-Delay Streaming Codes
Ahmed Badr, Pratik Patil, Ashish Khisti +2
We propose a new class of error correction codes for low-delay streaming communication. We consider an online setup where a source packet arrives at the encoder every channel u…
Robust Streaming Erasure Codes based on Deterministic Channel Approximations
Ahmed Badr, Ashish Khisti, Wai-Tian Tan +1
We study near optimal error correction codes for real-time communication. In our setup the encoder must operate on an incoming source stream in a sequential manner, and the decoder…
Streaming-Codes for Multicast over Burst Erasure Channels
Ahmed Badr, Devin Lui, Ashish Khisti
We study the capacity limits of real-time streaming over burst-erasure channels. A stream of source packets must be sequentially encoded and the resulting channel packets must be t…
The Streaming-DMT of Fading Channels
Ashish Khisti, Stark Draper
We consider the sequential transmission of a stream of messages over a block-fading multi-input-multi-output (MIMO) channel. A new message arrives at the beginning of each coherenc…
