摘　　要：最小均方(LMS)算法在自适应天线阵列计算中广泛应用,但采用FPGA实现时,由于其严格的执行流程,无法充分利用FPGA的并行计算优势,限制了信号实时处理速度。为了解决这一问题,文章采用一种延迟最小均方(DLMS)算法,并在FPGA平台实现该算法。仿真结果验证了该算法的可行性。The least mean square(LMS) algorithm is widely used in the calculation of adaptive antenna array. However, when it is implemented by FPGA, the parallel computing advantage of FPGA cannot be fully utilized due to its strict execution flow, which limits the real-time signal processing speed. In order to solve this problem, this paper adopts a delay least mean square(DLMS) algorithm and implements the algorithm on FPGA platform. Simulation results verify the feasibility of the proposed algorithm.
