Fig. 12From: Rotating cluster mechanism for coordinated heterogeneous MIMO cellular networksAverage achievable sum rate vs. K c with proportionally fair (PF) scheduling (t c =40) over the area of a macrocell in an arbitrary cluster, comparing various T cl for proposed rotating clustering scheme and fixed clustering for three-cell layout, using simulated annealing scheduling and SZF-DPC precoding.
