Information and communication with each passing day, the prospect of unlimited wireless technology. Over the past decade, wireless communication has been the rapid development, accompanied by a sharp increase in mobile communications and personal wireless communication number of users, traffic and data rates continue to increase, the communication system resource utilization requirements are correspondingly more demanding. However, after decades of fully tap the potential of frequency, time and coding technology almost to the extreme, to further enhance the space it has been subject to greater restrictions, the development of space resources become the focus of industry attention, smart antennas and other multi-antenna antenna technology emerged to become one of the key technologies of various types of new communication systems. Smart antenna technology to extend the radar and adaptive antennas used in wireless communications, intelligent array antenna current by adjusting amplitude an
