Abstract: there is a rapid growth in cellu lar networks due to the huge turnout for it, but all this happening without the current generations being fully utilized in terms of spectrum. Due to the nature of the cellular system where areas are divided into cells that have limited capacity, some area s might have larger populations causing the full utilization (congestion) of the cell whereas other areas might be serving a far less user base leading to the underutilization of the cell meaning that the overall system isn’t utilized properly. In order to solve this problem load balancing has been proposed with different approaches that ranged from tinkering with the cell reselection parameters or the cell’s shape and coverage. However these methods have failed to catch on thus far for a number of reasons and load balancing is still currently done manually using radio engineers. In our research we explore a mathematical model for load balancing in 4G LTE networks. We have proposed the addition of Wi

Abstract: The demand for wireless systems has been growing rapidly over the recent years due to improved reliability, high data rates, seamless connectivity and low deployment costs. MIMO systems are the most efficient leading innovation of wireless systems for maximum capacity and improved quality and coverage. Multiple Input Multiple Output (MIMO) in combination with Orthogo nal Frequency Division Multiplexing (OFDM) can provide spectrally efficient and ISI free communication. The Fractional Fourier transform (FrFT), as a generalization of the classical Fourier Transform, was introduced many years ago in mathematics literature . In this paper selecting the optimal order of the fractional Fourier transform, the modulated signals can match the time - varying channel characteristics, which results in a mitigation of the inter carrier interference. Furthermore, an algorithm is present ed for selecting the optimal order of fractional Fourier transform, and the impact of system parameters on the opt
