Summary: | 碩士 === 國立臺灣科技大學 === 電子工程系 === 105 === In this thesis, we consider the cloud radio acess network(CRAN) with finite fronthaul capacity architecture, which includes a centralized BBU pool, full-duplex remote radio heads(RRHs) and a set of half-duplex downlink and uplink mobile users. Compared to half duplex model, in this signal model, we have to manage new interference sources(self-interference, uplink to downlink interference), so the transmit (RRHs)-receive (BBU) beamforming and power control are used.
Our target is to solve the power minimization problem of full duplex cloud radio acess network(FD-CRAN) with finite fronthaul capacity under SINR and fronthaul capacity constraints. Therefore, the alternating optimization(AO) and Uplink-Downlink Duality strategies are proposed. Simulation results are presented to evaluate the proposed algorithms.
