In this work, the major impairment regarding the coverage and capacity of GSM system has been explained. This paper presents the adaptive antenna array systems as a promise technology that have the ability to overcome the mobile communication performance limitations.
The major contribution of this paper is to estimate the coverage, the blockage probability, and capacity improvement during the use of adaptive antennas in GSM base stations. MATLAB 6.5, has been used for simulation and performance improvement evaluation of capacity and coverage in the GSM system.
The results show that an adaptive antenna array of eight elements has a potential to reduce the outage probability, and improve coverage extension by about 280% and capacity by 40%.
