Fractional Frequency Reuse is an interference mitigation technique well suited for OFDMA system where the cell region is partitioned into two: inner cell region and outer cell region. In this paper we proposed an interference mitigation technique in LTE OFDMA femtocell system using Fractional Frequency Reuse (FFR) also system in order to improve performance of the system resource allocation is ...

Frequency domain adaptive antenna array (FDAAA) is an effective method to suppress interference caused by frequency selective fading and multiple-access interference (MAI) in single-carrier (SC) transmission. However, the performance of FDAAA receiver will be affected by the antenna placement parameters such as antenna separation and spread of angle of arrival (AOA). On the other hand, hybrid f...
