Description: 由上述实验过程的图像变化可知，经过傅立叶变换和反变换及DCT离散余弦变换和反变换后，图像都发生了很大的变化，首先是经过2-D傅立叶变换后，图像数据频域出现高频数据集中，低频数据在四周的现象，然后再经过2-D傅立叶变换反变换后，图像再次恢复原始图。而2-D离散余弦变换对图像的影响也是如此。

Description: QPSK Transmitter and I/Q Correlator Receiver is based on the technique of queing the information in a bit stream and on the receving end using FFT and some additive filters, as the addition of noise is made to infuse the need of a filter. Necessarily a Baseband filter is used. Modulation acheived at the receiving end.

And 2-D discrete cosine transform on the impact of images is also true.
