对ofdm插入梳妆（comb)导频，比较了有ls信道估计和无信道估计，并仿真得到了不同信噪比下，误码率曲线；信道为多径瑞利衰落加上白噪声；经过调试，已经能正确运行(Insert the dressing on the OFDM (comb) Pilot compared ls has no channel estimation and channel estimation, and simulation have been under different signal to noise ratio, bit error rate curve channel for multipath Rayleigh fading plus white noise after debugging have been able to run correctly)

非常经典的brew应用。功能非常强大！而且很实用-A very classic brew applications. Is very powerful! And very practical

实现二值化，当像素值（r+g+b）/3>128时设为255,当像素值小于128时设置为0.做归一化处理后，2值化的颜色 1为白，0为黑。边缘部分，计算有误差，255,254,253,252 就算白，0，1，2，3，4就算黑。屏幕显示时，肉眼是分辨不出这点误差的。你可以对2值化后的图像值作归一化处理，得到1和0，然后再放大（乘255），就可得到满意的数值。至于左边界上 1 254 253， 0 255 255，可能是2值化前，颜色原本就有差别。不是2值化的错误。

有非常详细的空域时域谱估计和波束形成算法，能够直接运行。包含了现在通用的AR/MUSIC等算法，非常好用。(There are very detailed spatial domain time domain spectral estimation and beamforming algorithms that can be run directly. It includes algorithms such as AR/MUSIC that are now common, and is very easy to use.)
