Analog Network Coding in the Generalized High-SNR Regime
In a recent paper, Maric et al. analyzed the performance of the Analog Network Coding (ANC) in a layered relay network for the high-SNR regime. They have proved that under the ANC scheme, if each relay transmits the received signals at the upper bound of the power constraint, the transmission rate will approach the network capacity. In this paper, the authors consider a more general scenario defined as the generalized high-SNR regime, where the relays at layer l in a layered relay network with L layers do not satisfy the high-SNR conditions, and then determine an ANC relay scheme in such network.
