Sum-rate maximization for cognitive radios in multi-user MIMO-OFDM context
international conference on electrical sciences and technologies in maghreb, 2018.
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
