The filter should also ensure that we are not in a "poisoned message" situation by ensuring that the message has been reprocessed less than "n" times.
筛选器还应该确保消息的重新处理次数少于“n”次，从而确保没有遇到“中毒消息”的情况。
Moreover, corresponding to different filter length N and frequency vector setting modes(traditional symmetry or even symmetry), 4 types of all-phase half-band filters were designed.
并针对不同的滤波器长度N和频率向量的设置（传统对称或偶对称），设计出了4种全相位半带滤波器。
The neopoloarographic synthetic data test indicated that 1 :N adaptive Kalman filter can compensate for modelling errors of system and resolve over- lapped response signals.
通过拟合实验数据表明，1：N 自适应卡尔曼滤波器与快速傅里叶变换和标准加入法相结合，用于补偿系统的模型误差和进行重叠峰的分辨，效果良好。
