基于椭圆球面波脉冲组的多进制PPM-UWB系统(M-ary PPM-UWB systems using pswf pulse group)

模拟2个独立窄带信号分别以20°，60°的方向入射到均匀线阵上，信号间互不相关，与噪声相互独立，噪声为理想高斯白噪声，阵元间距为入射信号波长的1／2，快拍数为200，信噪比为20dB，阵元数分别为10，50，100。 (Simulate two independent narrowband signals in the direction of 20 °, 60 ° of the incident on the ULA, among signal unrelated, independent noise, the noise is ideal Gaussian white noise, the array element spacing of the incident signal wavelength of 1/2, the number of snapshots 200, SNR is 20dB, the array element number 50, 100, respectively.)

说明：  按照信息论基本原理的解释，信息是系统有序程度的一个度量，熵是系统无序程度的一个度量；如果指标的信息熵越大，该指标提供的信息量越大，在综合评价中所起作用理当越大，权重就应该越高。因此，可利用信息熵这个工具，计算出各个指标的权重，为多指标综合评价提供依据(According to the interpretation of the basic principles of information theory, information is a measure of the order degree of the system, and entropy is a measure of the disorder degree of the system. If the larger the information entropy of an index is, the greater the amount of information provided by the index is, and the greater the role it plays in the comprehensive evaluation, the higher the weight should be. Therefore, we can use the tool of information entropy to calculate the weight of each index and provide the basis for multi index comprehensive evaluation)
