连续相位调制信号(CPM)产生，实现了对10个数字音的识别，实现了对10个数字音的识别程序详细画出了时域和频域的相关图，预报误差法参数辨识-松弛的思想，数据模型归一化，模态振动，多姿态，多角度，有不同光照。- Continuous phase modulation signal (CPM) to produce, To achieve the recognition of 10 digital sound, Realization of 10 digital audio recognition program Correlation diagram shown in detail the time domain and frequency domain, Prediction Error Method for Parameter Identification- the idea of relaxation, Normalized data model, modal vibration, Much posture, multi-angle, have different light.
