采用8PSK调制，用因子图进行均衡，系统无编码，加性高斯白噪声(Using 8PSK modulation, equalization of factor graph, the system without coding, additive white Gaussian noise)

matlab HTT文档 关于故障处理，里面用到了线性插值，结果以磁盘文件形式输出 (matlab HTT ducuments)

2元BPSK调制加高斯信道硬判决统计误码率(2 yuan plus Gaussian channel BPSK modulation hard decision error rate statistics)

非常适合计算机视觉方面的研究使用,含噪脉冲信号进行相关检测,多抽样率信号处理。( Very suitable for the study using computer vision, Noisy pulse correlation detection signal, Multirate signal processing.)

数字基带系统将数字信号从时域上看时数字滚降，需要画出滚降前后的波形展示出来。频域上带宽变化了。输入滤波器之前的波形与采样判决之后的波形。采样判决前的频谱。 采样判决后的码型。 2、眼图（采样判决之前的眼图）（信噪比大眼图清晰） 3、误码曲线，（横坐标时信噪比，纵坐标时误码率） 4、Arfa变化对误码特性的影响，变好还是变差(变好)，眼图清晰度变化（清晰），传递函数的带宽的变化。（带宽越大）(1.Digital baseband system point of view the digital signal from the time domain when the number of roll-off, you need to draw the waveform displayed before and after the roll-out. The frequency domain, the bandwidth change. Input filter and sample ruling before the wave after wave. Sample pre-judgment spectrum. Sampling pattern after the verdict. 2, the eye diagram (eye before sampling decision) (SNR big eye clear) 3, the error curve (abscissa when the signal to noise ratio, bit error rate when the vertical axis) 4, Arfa impact of change on BER performance, get better or worse (getting better), change of eye-definition (clarity), the transfer function of the bandwidth changes. (The greater the bandwidth))

基于harris 的图像角点提取，并做改进，限制小区域内最多特征点数量(feature extraction by harris)
