碩士 === 國立臺灣科技大學 === 電子工程系 === 107 === In this thesis, we consider a cloud radio acess network (CRAN) with nite fronthaul capacity architecture, which includes a centralized baseband unit (BBU) pool and a set of full-duplex (FD) remote radio heads (RRHs) serving a set of half-duplex (HD) downlink and uplink mobile users. Our goal is to minimize total transmit power of RRHs and uplink mobile users under each SINR and fronthaul capacity constraints. First, we consider a per-base-station successive interference cancellation (SIC) scheme that performs Wyner-Ziv compress-and-forward at RRHs, we use half-duplex system model at RRHs and derive achievable rate for uplink users under nite fronthaul link. Further we use full-duplex system model at RRHs, compared to half-duplex model, now we have to manage the interference such as self-interference, inter- RRH interference and uplink to downlink interference. Secondorder cone program (SOCP) based algorithm is proposed to solve power minimization problem and Uplink-Downlink Duality strategies is proposed to reduce calculation complexity. Simulation results are presented to evaluate the proposed algorithms.
