Abstract: Orthogonal Frequency Division Multiple Access (OFDMA) is a promising multiple access technique for next generation wireless communication such as WiMAX, LTE, IMT-A etc because of its high spectral efficiency and inherent robustness against frequency selective fading. Recently fem to cell has been proposed for indoor coverage extension and to reduce traffic within macrocells. Fem to cells are deployed in an ad-hoc manner by different consumers in the same frequency band, causing interference with each other. To fully realize the potential of these networks, it is necessary to allocate resources to them in such a way that interference is mitigated. This work aims to improve the performance of uplink OFDMA fem to cell networks by joint subchannel and power allocation. Joint subchannel and power allocation using Hungarian and water filling algorithm performs better than the existing fem to cell resource allocation algorithms with respect to spectral efficiency.
