| Abstract: | FPGA-based implementation of LMS algorithm is one of the key techniques in the application of adaptive array antennas. This paper proposes a method for implementing the fixed-point LMS algorithm based on FPGA . On the premise of satisfying the real-time quality of the system, it's comparatively easy to implement the method, and the precision and dynamic range of the algorithm can be ensured definitely. Finally, the simulation results show that this method is feasible. |
