雷达数字接收机正交解调的matlab仿真IQ

bfgs算法中需要用到的步长规则嗬嗬嗬嗬(the BFGS method)

说明：  加信噪声，单边带调幅，设计波特滤波器，过滤噪声，比较经过希尔伯特变换前后的区别(Plus letter noise, single-sideband amplitude modulation design Potter filters, filter noise comparison, after the difference between before and after the Hilbert transform)

说明：  兰伯特投影变换，可将大地坐标与兰伯特坐标系左边相互转换(Lambert projection transformation)

提取数据波形时域特征（绝对幅值、平均值、峭度、过零点）并且用LDA分类(Time-domain waveform data extraction features (absolute amplitude, mean, kurtosis, zero crossing) and classification with LDA)
