Abstract: FPGA-based implementation of floating-point LMS algorithm is one of the key techniques in the engineering design of adaptive array antennas. This paper proposes a new method to implemente floating-point LMS algorithm on FPGA . This proposed method adopts three levels of pipelines, satisfying the demand of precision and dynamic range of the algorithm concurrently. Simulation results show that the method can use FPGA logic resources efficiently and and assure the system running on high speed. Moreover, the method could satisfy real-time quality of the system.
