Optimal relay functionality for SNR maximization in memoryless relay networks
Optimal relay functionality for SNR maximization in memoryless relay networks
We explore the SNR-optimal relay functionality in a mernoryless relay network, i.e. a network where, during each channel use, the signal transmitted by a relay depends only on the last received symbol at that relay. We develop a generalized notion of SNR for the class of memoryless relay functions. The …
