Low Complexity Graphical Framework and Power Optimal Solution for Resource Allocation in LTE Network

The objective of the proposed project work is Downlink resource allocation for OFDMA-based next generation wireless networks subject to inter-cell interference (ICI). The main aim of the project is balanced performance improvement between cell edge and cell centre users. The resource allocation scheme consists of radio resource and power allocation, which are implemented separately. To achieve radio resource allocation, the low complexity heuristic algorithms are proposed, where graph based frame work and fine physical resource block PRB assignment are performed to mitigate ICI and improve the network performance. The power allocation performs to optimize the performance of cell edge users under the condition of the desirable performance of cell centre users.
