This script will attempt to find the band gaps in a phononic crystal by carrying out a Plane Wave Expansion of the various quantities It is for an acoustic wave equation with pressure instead of the displacement as prescribed in App. Phys. Lett. 70 3218 There are 3 programs, one for short, one for elastic long and the other one is for acoustic long(This script will attempt to find the band gaps in a phononic crystal by carrying out a Plane Wave Expansion of the various quantities It is for an acoustic wave equation with pressure instead of the displacement as prescribed in App. Phys.

1.设计自适应信号分离器，用以从白噪声中提取周期信号。其中选取正弦信号s=sin(2*pi*t/10)为周期信号，宽带噪声信号为高斯白噪声，设置参考通道延迟为50。 2.宽带信号中的窄带干扰抑制实际上是自适应信号分离的一种应用，借助自适应信号分离器可以方便的实现窄带干扰的对消。(1. Design of adaptive signal separator, used to extract from the white noise periodic signal. The extraction of sinusoidal signals s = sin (2* pi* t/10) for periodic signals, broadband noise signal is Gaussian white noise, set the reference channel delay of 50. 2. Wideband signals in the narrow-band interference suppression is actually an application of adaptive signal separation, using adaptive signal separator can be easily achieved narrowband interference cancellation.)
