相位误差对ＭＵＳＩＣ影响

说明：  MUSIC方法是Schmidt 在 1979 年首先提出的,并于1986 年重新发表。该方法和 Roy 于1986 年提出的 Esprit方法都是早期经典的超分辨率 DOA 估计方法 即超瑞利限的方法 ,他们同属特征结构的子空间方法。(MUSIC method is Schmidt first proposed in 1979, and re-released in 1986. The method and Roy in 1986, Esprit proposed methods are early classic super-resolution DOA estimation method that is super-Rayleigh limit of the method, they belong to the same characteristic structure of the subspace method.)

Designs a linear phase FIR lowpass filter such that it: - minimizes the filter order - has a constraint on the maximum passband ripple - has a constraint on the maximum stopband attenuation (This is a quasiconvex problem and can be solved using a bisection. minimize filter order n s.t. 1/delta <= H(w) <= delta for w in the passband |H(w)| <= atten_level for w in the stopband where H is the frequency response function and variable is the filter impulse response h (and its order/length). Data is delta (max passband ripple) and atten_level (max stopband attenuation level). )

matlab上倒谱的两种实现方式。一个是调用rceps（）函数来实现，另一个是根据定义来实现。两种方法画出的倒谱图一样。 附件中包含要处理的数据，该数据为加速度数据。(matlab on the cepstrum of two implementations. One is called rceps () function, and other is by definition to achieve. Draw the two methods as the inverted spectrum. Annex contains data to be processed, the data for the acceleration data.)

The idea is from "The Blur Effect: Perception and Estimation with a New No-Reference Perceptual Blur Metric" Crété-Roffet F., Dolmiere T., Ladret P., Nicolas M. - GRENOBLE - 2007 In SPIE proceedings - SPIE Electronic Imaging Symposium Conf Human Vision and Electronic Imaging, É tats-Unis d Amérique (2007)(Measure the blur level of still image.)
