稀疏分数阶傅里叶变换例子，线性调频信号的例子，分数阶傅里叶变换检测(Sparse fractional Fourier transform examples, linear frequency modulation signal example, fractional Fourier transform detection)

Linear prediction (LP) is an ubiquitous analysis method in speech processing. Various studies have focused on sparse LP algorithms by introducing sparsity constraints into the LP framework. Sparse LP has been shown to be effective in several issu

先输入数据生成相应的字典，再输入检测信号后得到用字典稀疏表示的结果(First input data, generate the corresponding dictionary, and then input the detection signal to obtain sparse dictionary results)
