Abstract The LMS algorithm is widely used in various signal processing fields such as radar, communication, etc. due to its simplicity. It is a focus in the research on the implementation of the high-speed adaptive filter. Based on the parallel pipelined LMS (PIPLMS) algorithm, a high-speed filter implementation is proposed in this paper. This implementation has both the properties of high pipelining in the systolic structure and parallelism in the parallel structure. At the same time, the implementation presented herein also has the properties of higher throughput rate, lower power consumption, larger step size range maintained convergence behavior and faster convergence speed.
