WSEE Optimization Using Asynchronous ADMM for Massive MIMO Two-Way Relaying

We decentrally optimize the weighted sum energy efficiency (WSEE) of a multi-pair two-way half-duplex massive multi-input multi-output relaying. We use asynchronous alternating direction method of multipliers (aADMM) optimization approach, which is robust to node delays and failures. We analytically...
