说明：  经典的SIFT算法，第一步，选择感兴趣的点；第二步，对感兴趣点进行筛选，确定关键点；第三步，为关键点分配方向；第四步，用多维向量的形式描述关键点(Classical SIFT algorithm, the first step, select the point of interest second step, points of interest were screened to identify key points the third step, the key point for the distribution of direction The fourth step is described with the key in the form of multi-dimensional vector point)

瑞历信道下误码率估计的盟特卡罗仿真，GUI显示，方便高效(Switzerland calendar channel bit error rate estimated UNITA Carlo simulation, GUI, facilitate efficient)

产生两个均值为m,方差为sgma的高斯随机变量，当输入参数只有一个时，认为均值为0。(mean to have two m, sgma variance for the Gaussian random variables, when only one input parameters, that the mean of 0.)

PSK31 Model with Symbol Timing and Carrier Recovery(This model implements a communication standard known as PSK31. The transmit portion of the model can either synthesize the PSK31 signal, or use real world signals that were captured as Wave files. The receiver features include: Automatic Frequency Control, Automatic Gain Control, Symbol Timing recovery with a fractionally spaced Farrow interpolator, Decision Directed Carrier Phase Lock Loop, dbsk or dqpsk demodulation with FEC. References are provided in the Model.)
