Can Marton Coding Alone Ensure Individual Secrecy?
Jin Yeong Tan, Lawrence Ong, Behzad Asadi
For communications in the presence of eavesdroppers, random components are often used in code design to camouflage information from eavesdroppers. In broadcast channels without eav…
The Secure Two-Receiver Broadcast Channel With One-Sided Receiver Side Information
Jin Yeong Tan, Lawrence Ong, Behzad Asadi
This paper studies the problem of secure communcation over the two-receiver discrete memoryless broadcast channel with one-sided receiver side information and with a passive eavesd…
Centralized Caching with Unequal Cache Sizes
Behzad Asadi, Lawrence Ong, Sarah J. Johnson
We address a centralized caching problem with unequal cache sizes. We consider a system with a server of files connected through a shared error-free link to a group of cache-enable…
A Simplified Coding Scheme for the Broadcast Channel With Complementary Receiver Side Information Under Individual Secrecy Constraints
Jin Yeong Tan, Lawrence Ong, Behzad Asadi
This paper simplifies an existing coding scheme for the two-receiver discrete memoryless broadcast channel with complementary receiver side information where there is a passive eav…
The DoF Region of the Three-Receiver MIMO Broadcast Channel with Side Information and Its Relation to Index Coding Capacity
Behzad Asadi, Lawrence Ong, Sarah J. Johnson
We consider the three-receiver Gaussian multiple-input multiple-output (MIMO) broadcast channel with an arbitrary number of antennas at each of the transmitter and the receivers. W…
A Unified Inner Bound for the Two-Receiver Memoryless Broadcast Channel with Channel State and Message Side Information
Behzad Asadi, Lawrence Ong, Sarah J. Johnson
We consider the two-receiver memoryless broadcast channel with states where each receiver requests both common and private messages, and may know part of the private message reques…
A Unified Scheme for Two-Receiver Broadcast Channels with Receiver Message Side Information
Behzad Asadi, Lawrence Ong, Sarah J. Johnson
This paper investigates the capacity regions of two-receiver broadcast channels where each receiver (i) has both common and private-message requests, and (ii) knows part of the pri…
Optimal Coding Schemes for the Three-Receiver AWGN Broadcast Channel with Receiver Message Side Information
Behzad Asadi, Lawrence Ong, Sarah J. Johnson
This paper investigates the capacity region of the three-receiver AWGN broadcast channel where the receivers (i) have private-message requests and (ii) may know some of the message…
Coding Schemes for a Class of Receiver Message Side Information in AWGN Broadcast Channels
Behzad Asadi, Lawrence Ong, Sarah J. Johnson
This paper considers the three-receiver AWGN broadcast channel where the receivers (i) have private-message requests and (ii) know some of the messages requested by other receivers…
On Index Coding in Noisy Broadcast Channels with Receiver Message Side Information
Behzad Asadi, Lawrence Ong, Sarah J. Johnson
This letter investigates the role of index coding in the capacity of AWGN broadcast channels with receiver message side information. We first show that index coding is unnecessary…
The Capacity of Three-Receiver AWGN Broadcast Channels with Receiver Message Side Information
Behzad Asadi, Lawrence Ong, Sarah J. Johnson
This paper investigates the capacity region of three-receiver AWGN broadcast channels where the receivers (i) have private-message requests and (ii) know the messages requested by…
