Asymptotic Capacity of Orthogonal Multi-Level Amplify-and-Forward Relay Networks

This paper analyzes the capacity of a wireless relay network composed of a large number of nodes that operate in an amplify-and-forward mode and that divide into a fixed number of levels. The source and relays are only allowed to operate at given time slots, while the destination can receive signals all the time. The capacity computation relies on the study of products of large random matrices, whose limiting eigenvalue distribution is computed via a set of recursive equations.
