In this paper, we study resource allocation for full-duplex communications in an orthogonal frequency division multiple access femtocell network. We aim to maximize the throughput of the femtocell while avoiding severe inter-tier interference to the macrocell via joint sub-channel assignment and power allocation. To be more practical, we take channel estimation error into account and use the robust...
This paper investigates simultaneous wireless information and power transfer (SWIPT) in a multi-antenna relay network. We consider robust transmit power minimization problem at the relay by jointly optimizing beamforming and adaptive power splitting subject to the signal-to-inference-plus-noise (SINR) and energy harvesting constraints by incorporating channel uncertainty model. We formulate the original...
