Resource Allocation for Multi-Cell OFDMA Based Downlink Network
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 3, Issue 5
Abstract
This paper presents best method for management of resource allocation to OFDMA (Orthogonal Frequency Division Multiplexing) based multi cells which are subjected to Inter Cell Interference (ICI) from adjacent cells. This paper implements allocation of resources that is frequency allocation and power allocation separately to provide quality of signals and compatible power to cell edge users. So to achieve frequency allocation Lowcomplexity heuristic algorithms are first proposed. To mitigate Inter Cell Interference (ICI) graph-based framework and fine physical resource block (PRB) assignment are performed and hence improve the network performance. After having frequency allocation then we will have a good allocation scheme for power distribution which is distributive to optimize the performance of cell edge users under the condition that desirable performance for cellcenter users must be maintained. Then Lagrange method is used to solve iterative barrier-constrained water-filling problem which is formulated by power optimization. Finally from simulation results our proposed scheme can achieve significantly balanced performance improvement between cell-edge and cell center users in multi-cell networks compared with other schemes, and therefore by adopting this scheme for resource allocation we can provide good performance to anyone from anywhere.
