Subnetwork Selection of Gaussian Relay Network   [Poster]
In wireless communication, some relays can be turned off while the optimal capacity still holds. We can apply traversing search approach to find the trimmed network, but its time cost might be unbearable. To solve the problem, we thoroughly study and rigorously prove properties of layered Gaussian relay network. We then develop and implement an algorithm that can find optimal global subnetwork exponentially faster.
