Abstract:
A monotonic optimization method is for achieving the maximum weighted sum-rate in multicell downlink MISO systems. It belongs to the wireless communications field. The weighted sum-rate maximization is viewed as a monotonic optimization problem over the achievable rate region. A sensible search scheme, a sequential partition method as well as a vertex relocation method are designed to reduce the complexity and accelerate the convergence.
