| Abstract: | The adaptive antennas array has the function of controlling the direction of the array real-timely,it can make the main beam of antennas array point to the direction of the expected signal and the null point to the direction of the interfering signal,so the adaptive antennas array has became more and more high regarded in military and civil communications system.The block diagram of complex LMS algorithm of the adaptive antennas array based on FPGA is given in this paper in detail,And the algorithm analyzes the performance.Finally it is showed that the algorithm has the better performance of interference suppression via simulation. |
