fir_lin_phase_lowpass_max_atten
Designs a linear phase FIR lowpass filter such that it:
- minimizes maximum stopband attenuation
- has a constraint on the maximum passband ripple
This is a convex problem (when sampled it can be represented as an LP).
minimize max |H(w)| for w in the stopband
s.t. 1/delta <= |H(w)| <= delta for w in the passband
( where H is the frequency response function and variable is
h (the filter impulse response). delta is allowed passband ripple.
)

针对稀疏圆阵的波达方向估计问题，提出了解相干求根MUSIC算法（Sparse UCA Decorrelation Root-MUSIC，SDR）。通过改进传统的波束变换方法，进行相位校正，并在波束域进行误差补偿，得到具有共轭对称结构的波束域导向矢量。在波束域进行前后向平均处理和使用求根MUSIC算法(In order to solve the direction of arrival estimation of sparse circular arrays, a new understanding of the Sparse UCA Decorrelation Root-MUSIC (SDR) algorithm is proposed. By improving the traditional beam transform method, phase correction, and error compensation in the beam domain, a beam-domain steering vector with a conjugate symmetry structure is obtained. Averaging forward and backward in the beam domain and using the root-finding MUSIC algorithm)
