将随意肌电图（EMG）作为肌电控制功能性电刺激器（FES）的控制信号，需要减少刺激伪影和非随意贡献（M波）。本文提出了一种能够有效去除随意肌电信号中M波的Gram-Schmidt（GS）预测误差滤波器（PEF）。此外，所提出的GS PEF实现在现场的可编程门阵列（FPGA）的实时处理和性能进行了测试与模拟和真实的信号。实验结果表明，GS-PEF能有效地降低M波，保留随意肌电。
To use the voluntary electromyogram (EMG) as a control signal of the EMG controlled functional electrical stimulator (FES), it is required to reduce the stimulation artifact and non-voluntary contribution (M-wave). In this study, a Gram-Schmidt (GS) prediction error filter (PEF) that can effectively eliminates the M-wave from voluntary EMG is presented. Also, the presented GS PEF is implemented on the field the programmable gate array (FPGA) for real-time processing and the performance is tested with simulated and real signals. Experimental results showed that GS-PEF was effective in reducing M-wave and preserving voluntary EMG.
