CS8955_RDS
- RDS(Radio Data System)数据广播系统是将数字信号调制到调频波段 (87.5~108MHz)并以广播的形式发送的一种信号传输系统。这种传输模式在北美 和欧洲得到了采用,而且得到越来越多的其他国家的关注。在北美和欧洲 都有 相应的标准,即RBDS 和RDS。 传输数据时,数据加载到57KHz 的副载波频段。副载波经过调制以适应固定 的双相编码信号。这个副载波经过抑制以避免调制后的数据在锁相环立体声解码 器中产生混叠同时还要与德国同样采用57KHz 频率作为

- 针对滚动轴承复合故障信号特征难以分离的问题, 提出将双树复小波变换和独立分量分析( ICA) 结合的故障诊断方 法 该方法首先将非平稳的故障信号通过双树复小波变换分解为若干不同频带的分量 由于各个分量存在一定的频率混叠, 对 故障信号特征提取有很大的干扰, 进而引入 ICA 对各个分量所组成的混合信号进行盲源分离, 从而尽可能消除频率混叠 最后 对从混合信号中分离出来的独立分量信号进行希尔伯特包络解调, 即可实现对复合故障特征信息的分离和故障识别-Aiming at the diff
