The Research Of Smart Antennas Beamforming Based On Wavelet Field

Smart antennas beamforming technology is spatial digital processing technology, which method is that the main beam of antennas array pattern formed by adjusting the weight coefficients of sensor antenna point to the signal-of-interests and the zero pouch direct to the interferers. It is one of the key technology of 3G. It's applications can increase the capacity of system , improve link capability and length the ranging distance. So that it is hot research issue in communication field. Beamforming technology is very important for instructing both the theory and the applications in Sonar, Radar, Seismology and so onThe major contribution of this paper is summarized as follow: 1. According to the analytic model of smart antennas beamforming system, after studying on the work of predecessor, this paper present wavepacket transforming based beamforming algorithm ,carry out the emulation and compare it's performance with that of wavelet based beamforming algorithm...
