With the rapid development of wireless mobile communication networks, mobile phones have become an indispensable communication tool in people's daily lives. At the same time, market competition between the wireless communication operators has relentlessly increased. This competition has lead those operators to make on-going efforts to optimize their networks to provide better communication quality, and improved customer satisfaction leading to potential gains in market share.

On the one hand, increased capacity using new technologies, such as GPRS, EDGE and 3G, as well as the increased data traffic based on these technologies, has required stricter SNR (signal-to-noise ratio) in the wireless environment.

On the other hand, because of greater distribution and density of base stations as well as a growing number of legal and illegal installations utilizing of broadband technologies, various types of interference can be produced throughout communication systems and constrain the quality of the wireless network interface...
