Abstract:

An efficient allocation of the radio resources is an important issue in multi-user orthogonal frequency division multiplexing (MU-OFDM) systems. In this paper, we investigate the downlink resource allocation problem (subcarrier and power allocation) in MU-OFDM-based underlay cognitive radios networks (CRNs) using multipleinput-multiple-ou...More
