Cloud Radio Access Network (C-RAN) is a novel mobile network architecture which can solve lots of challenges in the next generation mobile communication system, including the demand for higher energy efficiency(EE). In C-RAN EE research field, most of recent work focuses on systematic energy saving and ignores the needs of users. To improve the performance of C-RAN under fronthaul capacity constraint,...
In this paper, a robust optimal distributed relay beamforming scheme is presented for two-way wireless relay systems with two sources (one base station and one mobile terminal) and multiple relays, each having a single antenna. Considering that the perfect channel state information (CSI) between the mobile terminal and the relays is usually not available, the new beamforming problem, based on the...
