Inter-cell interference mitigation using Intelligent Frequency Allocation-Dynamic Power Allocation in LTE systems

Abstract

Traditionally, all new emerging wireless technologies require wider bands than the existing ones. However, the frequency spectrum is a limited resource and to be utilized more efficiently. Therefore, the scarcity of the spectrum is a major problem that plays most important role in the growth of wireless communications and cost billion dollars business. Interference is an unwanted component of several of signals transmitted from different transmitters in wireless communication systems. In LTE system which uses reuse factor of one, which require whole available spectrum is used in each cell of the network. The areas falls in interference power dominant in comparison to required signal power. In the paper, Intelligent Frequency Allocation-Dynamic Power Allocation (IFA-DPA) is proposed. The algorithm is implemented on Cost-231 propagation model, The results obtained are very much promising to the inter-cell interference problem LTE networks and proved its usefulness.
