Investigation into LTE performance employing FFR and beamforming technology

The Long Term Evolution (LTE) technology is the most possible candidate for next generation mobile communications. One impairment of LTE is the interference from neighbor cells, so called Inter-Cell Interference (ICI). The Fractional Frequency Reuse (FFR) has been proposed to handle the problem. Also lately, soft FFR technique has been introduced for better utilization of frequency spectrum. In addition, beamforming technique is considered to be the solution to improve the performance of wireless communication systems. From literatures, the true performance of beam forming-LTE systems in term of signal quality has never been revealed. Therefore, this paper investigates into the mentioned performance in term of Signal-to-Interference plus Noise Ratio and channel capacity through computer simulation. The obtained results show that FFR technique including beam formation improves the system performance. Furthermore, employment of soft FFR provides the best performance to the beam forming-LTE systems.
