| Abstract: | The technology of adaptive beam forming is the key technology in smart antenna.Adaptive beam forming algorithms are used to produce directional beam based on the spatial information of users.The main beam aims at the coming direction of desired user and the side lobe or null points at the coming direction of interfering user.This paper introduces an adaptive beam former based on DSP and FPGA.This system can realize the real-time data processing and achieve the expected indices. |
