Secrecy capacity of a class of orthogonal relay eavesdropper channels
Vaneet Aggarwal, Lalitha Sankar, A. Robert Calderbank +1
The secrecy capacity of relay channels with orthogonal components is studied in the presence of an additional passive eavesdropper node. The relay and destination receive signals f…
Relay vs. User Cooperation in Time-Duplexed Multiaccess Networks
Lalitha Sankar, Gerhard Kramer, Narayan B. Mandayam
The performance of user-cooperation in a multi-access network is compared to that of using a wireless relay. Using the total transmit and processing power consumed at all nodes as…
Sum-Capacity of Ergodic Fading Interference and Compound Multiaccess Channels
Lalitha Sankar, Elza Erkip, H. Vincent Poor
The problem of resource allocation is studied for two-sender two-receiver fading Gaussian interference channels (IFCs) and compound multiaccess channels (C-MACs). The senders in an…
On the Sum-Capacity of Degraded Gaussian Multiaccess Relay Channels
Lalitha Sankar, Narayan B. Mandayam, H. Vincent Poor
The sum-capacity is studied for a K-user degraded Gaussian multiaccess relay channel (MARC) where the multiaccess signal received at the destination from the K sources and relay is…
