Secure Analog Network Coding in Layered Networks
Tulika Agrawal, Samar Agnihotri
We consider a class of Gaussian layered networks where a source communicates with a destination through intermediate relay layers with nodes in each layer in the presence o…
Analog Network Coding in Nonlinear Chains
Samar Agnihotri
The problem of characterizing the optimal rate achievable with analog network coding (ANC) for a unicast communication over general wireless relay networks is computationally hard.…
Beam-forming for Secure Communication in Amplify-and-Forward Networks: An SNR based approach
Siddhartha Sarma, Samar Agnihotri, Joy Kuri
The problem of secure communication in Amplify-and-Forward (AF) relay networks with multiple eavesdroppers is considered. Assuming that a receiver (destination or eavesdropper) can…
Secure Transmission in Amplify and Forward Networks for Multiple Degraded Eavesdroppers
Siddhartha Sarma, Samar Agnihotri, Joy Kuri
We have evaluated the optimal secrecy rate for Amplify-and-Forward (AF) relay networks with multiple eavesdroppers. Assuming i.i.d. Gaussian noise at the destination and the eavesd…
Analog Network Coding in General SNR Regime: Performance of Network Simplification
Samar Agnihotri, Sidharth Jaggi, Minghua Chen
We consider a communication scenario where a source communicates with a destination over a directed layered relay network. Each relay performs analog network coding where it scales…
Analog network coding in general SNR regime: Performance of a greedy scheme
Samar Agnihotri, Sidharth Jaggi, Minghua Chen
The problem of maximum rate achievable with analog network coding for a unicast communication over a layered relay network with directed links is considered. A relay node performin…
