A unified framework for the joint optimal allocation of subchannel and power in multi-hop relay network

摘要

This paper provides a unified framework for the joint optimal subchannel and resource allocation in multi-hop relay network. Specifically, we use a simple rearrangement inequality and show that seemingly difficult problems can be efficiently solved. This includes several existing solution methods as special cases. The proposed framework can be applied to the MIMO relaying and multi-hop OFDM.
