Abstract :
This paper considers the resource allocation problem of Space Division Multiple Access (SDMA)/ Multiple Input Single Output (MISO)/Orthogonal Frequency Division Multiple Access (OFDMA) systems. Equal power allocation (EPA) is used among subcarriers to reduce the complexity of the problem. Furthermore, a novel algorithm called proportional rate greedy (PRG) is proposed to choose users and allocate powers among selected users for each subcarrier. Such EPA-PRG algorithm can be applied to different fairness issues. From simulation, it can both achieve high throughput and ensure the fairness among users without increasing the complexity.
