Abstract? Smart antennas are the systems which are useful for wireless environment. Smart antenna systems may revolutionize future communication systems. So far, only the spectrum, the time and the code domain are exploited for communications systems. In the fast, from a signal processing perspective, most Wireless networks have been Single Input and Single Output (SISO), with the sequential nature of SISO signal processing serving as a bottleneck that limits performance. However, processing multiple signals simultaneously through smart antennas could lead to substantial performance improvement. Using this new approach, researchers are exploring multiple Input and Multiple Output (MIMO) wireless technologies to improve end-to-end network throughput of multiple flows relative to SISO antennas. Smart antennas are widely used in wireless mobile communications as they can increase the channel capacity and coverage range. The proposed research suggests solutions for wireless communications an example of mobile environment into consideration.
