0. 基本概念

  • AWG:Additive White(zero-mean) Gaussian,可加白噪声;

    • AWGN:Additive White(zero-mean) Gaussian Noise
    • 将某一均值为 0 方差为大小的噪声序列,加到原始信号和传递函数卷积后的结果上,
    N, L
    AWG = sigma*randn(N+L-1, 1);
    y_hat = conv(y, h) + AWG

1. 滤波器设计

2. Gabor 滤波器

  • Gabor filter ⇒ Gabor features ⇒ oriented structure
