Description: 离散余弦变换(DCT)是一种常用的数字速率变换编码方法。DCT首先将整个图像分割成n×n像素块,然后在n×n像素块上逐帧执行DCT变换。由于图像的高频成分很小,与高频分量对应的系数通常为零,肉眼对高频分量的变化并不敏感, 因此,我们使会用简洁的定量方法。因此,数字传输系数的速率远小于用于传输图像像素的数字速率。到达接收机后,逆离散余弦变换返回到样本值。虽然会有一定的失真,但人眼是可以接受的。(The coefficients of the DCT domain motion compensation error or the original image information convert into blocks are represented by different frequency components. It has two advantages: first, signal 1, most of the energy in the small range is concentrated in the frequency domain. Such a description is an important part of several key points. Second, mapping the frequency domain decomposition process to the human visual system.)

Description: 通信系统的端到端学习是a
引人入胜的新颖概念迄今为止仅被验证
模拟基于块的传输。它允许学习
发射机和接收机实现为深度神经网络
(NN),它们针对任意可区分的端到端进行了优化

证明无线传输是可能的:我们建造,
训练,并运行完整的通讯系统

和开源深度学习软件库。(End-to-end learning of communications systems is a
fascinating novel concept that has so far only been validated by
simulations for block-based transmissions. It allows learning of
transmitter and receiver implementations as deep neural networks
(NNs) that are optimized for an arbitrary differentiable end-to-end
performancemetric, block error rate (BLER). In this paper, we
demonstrate that over-the-air transmissions are possible:We build,
train, and run a complete communications system solely composed
of NNs using unsynchronized off-the-shelf software-defined radios
and open-source deep learning software libraries.)

Description: 编码:
(1)进行颜色转换,将RGB格式转换为YUV格式。
(2)将待编码的N×N的图像分解成(N/8)^ 2 个大小为8×8的子图像。
(3)对每个子图像进行DCT变换,得到各子图像的变换系数。这一步的实质是把空间域表示的图像转换成频率域表示的图像。
(4)对变换系数进行量化。
(5)进行Z字形重排
(6)使用霍夫曼变长变码编码器对量化的系数进行编码,得到压缩后的图像(数据)。
解码:
(1) 对压缩的图像数据进行解码,得到用量化系数表示的图像数据。
(2) 进行反Z字型重排
(3)用与编码时相同的量化函数或量化值表对用量化系数表示的图像数据进行逆量化,得到每个子图像的变换系数。
(4)对逆量化得到的每个子图像的变换系数进行反向正交变换(如反向DCT变换等),得到(N/8)^2 个大小为8×8的子图像。
(5)将(N/8)^2 个大小为8×8的子图像重构成一个N×N的图像。
(6)进行颜色组合,将YUV格式转换为RGB格式图像。(JPEG compression and decompression process)
