Abstract

Telecommunication technology plays a vital role in everyone`s life. It becomes one`s necessity in life. In this millennium era, the number of telecommunication users increases drastically without any age limit. People have been frustrated, when the performance of the network does not fulfil their expectations. This leads to a dissatisfaction. Interferences between the cells is the root cause of this problem. Interferences occur when different customers are utilizing the same portion of the frequencies at the same geographic area and time. In this research, the focus would be on how to overcome this problem and also to improve the network performance. Since the recent technology that`s being newly introduced in Malaysia is 4G, so this project will focus on overcoming interferences in OFDMA Network. OFDMA provides flexibility in the development of frequency bands in a systems such as LTE and LTE Advanced. Fractional Frequency Reuse (FFR) is a method that is chosen to overcome interferences between cells in this research. FFR offers an alternative solution to the frequency reuse problem in multicellular OFDMA networks. FFR is developed as a flexible frequency reuse scheme to strike a better trade-off between spectral efficiency and interference mitigation than the generic frequency reuse.
