Power Spectrum Optimization for Interference Mitigation Via Iterative Function Evaluation
This paper proposes practical methods for and examines the benefit of dynamic power spectrum optimization for interference mitigation in wireless networks. The paper envisions a distributed antenna system, deployed as a means to increase the network capacity for areas with high data traffic demand. The network comprises several Access Nodes (AN), each serving a fixed set of remote radio units called Remote Terminals (RT). The RTs belonging to each AN are separated from each other using Orthogonal Frequency Division Multiple Access (OFDMA) over a fixed bandwidth, where only one RT is active at each frequency tone.
