In communication systems, we have to increase the reliability of the communication operation between transmitter and receiver while maintaining a high spectral efficiency. The ultimate solution relies in the use of diversity, which can be viewed as a form of redundancy . Multiple-input multiple-output systems include a variety of techniques capable of not only increasing the reliability of the communication but also impressively boost the channel capacity. In addition, smart antenna system can increase the link quality and lead to appreciable interference reduction. Smart antenna technology is one of the most vital developments in mobile communication. The signal that is been transmitted by a smart antenna cannot be tracked or received by any other antenna thus ensuring a very high security of the data transmitted.
