Abstract :
This paper is concerned with the downlink transmission in cognitive multiple-input single-output (MISO) multi-cell wireless networks. Subject to various interference tolerance and quality-of-services (QoF) constraints, the problem of sum rate maximisation is recast by concave programming, for which our previously developed Frank-and-Wolfe (FW) type algorithm is applicable and shown to achieve excellent performance.
