随着我国经济的快速发展,对石油的需求与日俱增。这对石油行业来说,既是机遇更是挑战。它要求石油人具备更强的专业知识和能力。因此它对石油专业的大学生提出了更高的要求。本次课程设计就是为了适应上述要求而开设的。它要求学生在熟练掌握理论知识的基础上,结合生产实践,自己独立完成一口井的采油设计。- Along with the our country economy fast development, grows day
by day to the petroleum demand. This said to the petroleum profession
that, since the opportunity is the challenge. It requests the
petroleum person to have the stronger specialized knowledge and the
ability. Therefore it set a higher request to the petroleum
specialized university student. This curriculum designs is for adapt
the above request to open. It requests the student skilled to grasp
the theory knowledge in the foundation, in coor with progress of
production practice, own independently complete a well the extraction
design.

构造一组输入为白噪声加三个频率非常接近的正弦波,其信噪比为10dB,观测长度为256。试分别用普通AR谱估计和采用功率噪声抵消算法的AR谱估计估计这组信号的频率,并比较结果。-constructed a group of white noise input plus three very close to the frequency sine wave, the signal-to-noise ratio of 10dB. Observing length of 256. Were used to test the general AR spectral estimation using power and noise canceling algorithm for the estimation of AR spectrum estimation of this group of signal frequency, and the results of the comparison.
