Capacity Analysis of OFDM/FBMC Based Cognitive Radio Networks With Estimated CSI

In this paper, the authors focus on the channel capacity analysis of a Cognitive Radio (CR) network using two types of multicarrier communications: conventional Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) and Filter Bank based Multi-Carrier (FBMC) modulations. They use a resource allocation algorithm in which subcarrier assignment and power allocation are carried out sequentially. By taking the impact of Inter-Cell Interference (ICI) resulting from timing offset into account, the maximization of total information rates is formulated, subject to maximum power constraint as well as interference constraint from Secondary User (SU) to Primary User (PU).
