Modulation Pattern Recognition of RF Signals Based on Two-Dimension Dispersed Fourier Transform 基于二维离散傅立叶变换的射频信号调制类型识别
According to two-dimension Fourier transform, the Rayleigh wave signal in time-space domain can be changed into two-dimension frequency wavenumber spectrum from which we can choose, pick up Rayleigh wave and suppress interference wave successfully. 利用二维傅式变换可以将时间&空间域的瑞雷波信号转换为二维频率波数谱,从中选择和提取瑞雷基波,有效地压制干扰波。
