该文针对具有两个相互重叠频率成分的密集频谱 ,分析了两个重叠频率成分在复频域的叠加情况 ,在不增加采样长度的条件下 ,通过向量分解和单频率成分的识别、校正方法 ,推导出其校正公式。-In this paper, with two overlapping frequency components of the dense spectrum of two overlapping frequency components in the frequency domain stacking situati

在不同采样频率下，对已知信号进行采样和滤波，本文附录了MATLAB程序及仿真结果。-At different sampling frequency, the sampled signal is sampled and analyzed, and the MATLAB program is introduced in this paper.

在带通采样条件下实现了QPSK信号的调制解调，并附有每一步的曲线图- U5728 u901A u901A u91C0 u6837 u673 u4E09 u4E0B u5B9 u3B0 u4E86QPSK u4FE1 u53F7 u7684 u8C03 u5236 u89Y3 u8E03 uFF0C u5E76 u9644 u6649 u6BCF u4E00 u6B65 U7684 u66F2 u7EBF u56FE
